It's been tried, they feed the evaluation into the LLM and get it to commentate.
The results are absolute garbage (as you would expect) since the LLM's really don't understand chess or how to play it, someone posted a benchmark of the current SOTA ones playing Chess and the best was estimated at 1480.
I think OP meant trash talking. "Nice knight on the rim you got there buddy." "How long do you think you'll be able to hold onto that pawn?" "The Latvian gambit, really?"
