Yes, what I said should be falsifiable. The burden is on you to give me an example, but I can give you an idea.

You need to show me an LLM applying writing techniques do not have examples in its corpus.

You would have to use some relatively unknown author, I can suggest Iida Turpeinen. There will be interviews of her describing her writing technique, but no examples that aren't from Elolliset (Beasts of the sea).

Find an interview where Turpeinen describes her method for writing Beasts of the Sea, e.g.: https://suffolkcommunitylibraries.co.uk/meet-the-author-iida...

Now ask it to produce a short story about a topic unrelated to Beasts of the Sea, let's say a book about the moonlanding.

A human doing this exercise will produce a text with the same feel as Beasts of the Sea, but an LLM-produced text will have nothing in common with it.

why are you bringing this constraint?
