Sounds like building something simple that aids in tracking “coverage” of reviewing ToSs could be useful to increase that the odds of spotting something untoward?

Iirc there was (is?) a site which gives a rating to the various license agreements of popular services and the like, so maybe it’s a solved problem?

I have the TOS;DR extension [1] and it gives a rating to each website's TOS and offers an explanation of the key points.
