There are certain basic presuppositions about texts: that they are written by humans who have some kind of basic concern with truth or aesthetics or both. A liar who writes falsehoods is still concerned with truth: someone who writes with a bad aesthetic is still concerned with aesthetics. A human being writing Oulipo poetry according to an automatic procedure is obviously concerned with aesthetics.
LLM produced texts are fundamentally not concerned with any of these things.
