alt Hacker NewsXerox already went through that lawsuit and won, which is why photocopiers still exist. The tool isn't in the wrong for being told to print out the copyrighted works. The user still had to make the conscious decision to copy that particular work. Hence, still the user's fault.
You take the copyrighted work to the printer, you don't upload data to an LLM first, it is already in the machine. If you got LLMs without training data (however that works) and the user needs to provide the data, then it would be ok.
