We don't train current LLMs to mimic the average human's writing style. We train it to be smart, helpful, and knowledgable, too knowledgeable for a human. We can easily train a LLM to pass the Turing test if we wanted to, but then it would just sound dumb or biased.

We have one of those: Grok.
Yes, and it's indistinguishable from the average X user.
Bold of you to assume they’re actual users.

Interesting idea. "This is not dumb and biased enough, probably not a human".
There is tons of money trying to get customer support bots to sound human but they fool nobody.
