We've had mechanical/automated/algorithmic transformation of copyrighted works for over 100 years now. There are plenty of non-AI systems for translating code from one language to another. In the context of shifting a program between programming languages LLMs are just another algorithmic transformation technology. In any case, shifting a program from one language to another is not some kind of magic copyright erasure technique, whether or not an LLM is used. The law has codified procedures to assess infringement. If mechanical means is used (i.e. an LLM) the output is literally a function of the input. Good luck.
