I never thought of that. Humans avoid machine code for many reasons. If LLM's don't need to produce human-readable output, then why not?

they can call tools to count tho?

I mean, is this an actual issue? There have to be plenty of developers using LLMs to write Lisp(s).

I have occasionally seen Claude models struggle to balance brackets/parens in nesting-heavy languages like Dart (Flutter), but it’s gotten much better.
