I think it's a valid question. Suppose you have two LLMs interacting with each other in a loop, and one randomly prompts the other to reproduce the entire text of Harry Potter, which the other then does. However, the chat log isn't actually stored anywhere, it's just a transient artifact of the interaction - so no human ever sees it nor can see it even in principle. Is it a copyright violation then? If it is, what are the damages?
