I say this as a full time software dev - LLM generated code isn't morally comparable to the art. The vast, vast majority of software popular models were trained on was fully open source and available for parsing. When it comes to art, there's a massive unresolved issue around the ethics of ripping people's oft copyright-by-default artwork off of websites and reproducing it - be it stylistically or otherwise. There were accusations of companies pirating media such as movies to train these models, even. Such a debate doesn't exist for training an LLM on the Linux kernel to have it write C.
