Anything involving a human being will be down to that person. That's life, nothing to do with MOT's
And MOT's are a very basic inspection. If you cant pass the test...something is badly wrong. If you know you have dodgy stretched tyres, then you should expect a fail so no reason to be pissed off if you do fail.

I don't run stupid stretch. 215,35,18 on an 8.0" rim, if you even call that stretchIf youre running tyres of that magnitude of stretch, failing an MOT is the least of your worrys on a list of "what could go wrong" tbh.
