Sorry to have been unclear - I did mean "clean room". But an LLM can easily jump through the loopholes currently required for that.

Regular humans train on copying code too (Stack Overflow, etc.) so unless they were trained on that specific codebase, I really doubt you have any sort of legal standing. And given how little compensation the authors got when their work got trained on, I wouldn't hold out hope for a big payout even then...
