Already a year ago I vibe coded Babelfish: https://github.com/bobjansen/Babelfish
It integrates an LLM of your choice with StockFish to analyze games. Back then, the results weren't very good and I abandoned the project but a lot has changed (the LLM's got better and I did too) so maybe it is time to take another stab at it.
LLMs have gotten better at things they've been heavily post-trained for; its really post-training that has gotten better.
