there probably already is, and it's deployed with a kill-switch one would hope at the HFT firms.
I don't have any insider knowledge but i'm pretty sure that one Quant group that everyone knows about probably figured out most of the "tricks" used to get llms and SD to really take off a decade before anyone else. iirc they consistently get like 30% or greater returns, which is practically black magic and means that they have something that can see a pattern(s) in the data.
