If your APNs are greyed-out you usually can still get to them via the e-screen (Google it) though I hear sometimes this doesn't work with some carriers. (One of the Windows phones -- I think it was the T-Mo 810 -- had this issue and Nokia posted one of those scan tags on their site that apparently un-greyed them).

From my experience with smart phones, I know if updates are done they can go through a lot of data. A software can hang while in the middle of some task that is using data and it can keep streaming in a loop. This once happend to me with a video software on my tablet. From what I have been informed third party software can be suseptable to this problem if not properly written (actually any software).
A big thing with smart phones is to make sure the data plan is large enough. It is recommended for most of these phones to have at least 2 GB of data available. When I am at home I have the phone set to WiFi for data. This way I don't use mobile data.
For each of our Z10's we have 3 GB or more data on the plan depending on how the particular phone will be used. For my phone I have 6 GB because I am often using it as a modem for an i7 laptop. For the phone part, last month I used over 2 GB from my estimate, and not including what I used for my laptop.

"I believe there must be a better way for the carrier to identify data usage. If they are unable to accurately determine tethered from on device data they should never have resigned my contract."
There isn't. Data is data, and that's the problem.
Most current model phones send control data to the carrier when they engage tethering mode (the Z-10 does so) and thus the carrier can reject it. Some change the APN "silently", which you will only catch through the phone's diagnostic screens. How this is done varies on a carrier-by-carrier basis, but this has become common over the last few years.
The problem is that this only applies to phones that are playing "nice" from the carrier's perspective.
A packet of data is a packet of data. It is not possible to know with certainty what generated it -- whether it's a tethered device or the phone itself. This creates a policy enforcement problem for the carriers and they've "solved" it through their hinky games with APN changes and similar. But they've backed that up with actual packet inspection to try to detect people they believe are "cheating."
In most cases where tethering is not included in a given plan it simply redirects any browsing attempts to an intercept screen that tries to upsell you on whatever the carrier adds to your account. But if you have a situation where the carrier doesn't prohibit tethering but instead charges a ridiculous amount of money for it then you run into the sort of problem you have seen if the carrier misidentifies what your phone is doing.
The carriers in the US have taken to all sorts of rather nasty (and really pretty evil) steps in an attempt to force people off legacy plans that have unlimited data buckets; one of the tricks here has been to introduce new APNs required for LTE service and then refusing to allow them to be used unless you forfeit your legacy unlimited data plan. No new APN, no LTE -- period. With the Z-10 this is especially evil because most carriers also locked the APN setting screen and thus you can be effectively prohibited from using the Zed at all on the legacy "unlimited" data plans! Another favored trick is to look at the IMEI prefix and refuse to allow newer devices to register on the older plans, usually for data service (that is, phone calls and text messages will work but nothing else.)
8GB of data on the device in a month, with nothing tethered to it, is a hell of a lot of data. It's pretty difficult to generate that must use with one exception -- if you are watching an awful lot of streaming video. And that may be part of the problem here -- the carrier may be expecting streaming video access to go to a "mobile" URL on the particular service (e.g. Youtube) and "catching" that it is not, considering that use tethered though in fact it isn't.
In the end the best option if you are never going to use tethering and have such a plan is to raise hell and demand that the carrier block alleged "tethering" rather than billing you at the per-megabyte rate. Virtually all carriers can do this through a flag on your account but of course they love billing you per-megabyte instead. Then the worst thing that happens is that you run into problems where your phone's data doesn't work right, and you can raise a stink about that separately.
