Replace LLM with 'young author'. If you feed a 'young author' the works of a famous current author, E.G. Rowling, and ask them to write a new work in the style of that reference author... Or if you include the current N 'Best Sellers' and ask them to write whatever's popular. I'm not so convinced creativity is any more magical than a naturally evolved and refined version of what computers are starting to approach. Humans naturally add far more background, results filtering, and implicit selection parameters (personal biases / preferences). Maybe the correct line is somewhere around; tracing (direct copying) is bad, but freehand (from memory) is OK. However computers inherently have more perfect memory than humans; how precise is the detail from the source work? Is there a meaningful threshold where the memory of a work has decayed from a representation of the source work?
