If you wanted to go all in, you'd want a language that is denser so you get more efficiency out of tokens. Since it's being used by LLMs, readability by humans can take a back seat. Obviously the answer is: Perl.
But seriously though, a high-level language designed for LLMs would be interesting, maybe with a translation layer to something more developer friendly on top.
High information density is good for LLMs. https://ash-hq.org benefits from this, but hurts due to being fairly new. https://hexdocs.pm/usage_rules is helping.

That's Lisp because nothing compresses the number of tokens you have to write more than Lisp Macros.
APL is the densest language I have come across.
There may not be enough code out there for LLMs to pick it up though.
