This is rich considering LLMs can't even write like an average person let alone famous authors

Wuddabout:

Works unfinished at the time of the author's death?

Abandoned works?

Lost works? Prompt: Aristotle's work on comedy has been lost. Write a short treatise on comedy, using Aristotle's methods as shown in his Corpus and especially his treatises on Rhetoric and Poetics.

Haven't they been doing this for a long time already? I remember trying to copy Hunter S. Thompson's style many moons ago and getting a refusal.

After it stole literally every authors style in existence…

Ask the LLM to describe that author's style. Then start a new chat and tell it what you want it to write, giving it the author's style as a guide but without mentioning the author. While I've never used it for this particular purpose, I've used variations of this technique to get around other blocks quite well.

What about public domain authored works style?

Another one of those interventions that'll just put US labs at a disadvantage. The public at large doesn't want to use models gimped so as to protect a bunch of pre-AI special interests who should adapt, not obstruct.
