I like library providers that can provide mechanical upgrade instructions. For example:

model.adjust(x,1,y) is now model.single(Adjustment.Foo, x).with_attribute(y)

Also you pay some of the maintenance burden by writing all this documentation, so you have a some stake in keeping the changes minimal.

If you are this early career and the company is still paying you, PIP or no PIP, it’s very likely that they want you to succeed. Question your assumptions and make sure you really understand the feedback they are giving you. Don’t put in extraordinary hours (you want to have clear judgement, get plenty of sleep) but look for every resource, mentors, books, ask for help, and focus on doing your best. This will put you in the best possible light no matter what happens.

The chess engine’s training is anchored by the win/lose outcome of the game. LLM training is anchored by what humans like to read and write. This means that a human needs to somehow be in the loop.
