I disagree. The LLM outputs really do lack anything original or interesting. They just produce banal copy whatever you ask them.

A good editor could probably reduce all LLM outputs on a subject down to the same point.

Nope, if you provide pages and pages of example of a style to imitate, it will do it and do it fairly well. Of course how well they do it differs from one model to the next, but providing context and extensive system prompt does change things every time.

Imitation is banal.
