How is "Any LLM" operationalized? Does it include scaffolded LLMs like AutoGPT, or things-that-are-structured-as-LLMs-but-trained-on-something-that-is-not-a-spoken-language like OthelloGPT?

Shouldn't the close date be 2025?

This is definitely something an llm cannot do, because chess is combinatorial while an llm requires data.
