I do think there is some association, because it seems there is little
use for a Elisp language server outside of these use-cases. When someone
wants to debug a broken configuration, they'd usually emacs -Q, not open

LSP has not existed for that long, and I am not sure if there were any
comparable projects of the same ambition before. At most "language
servers" have existed for specific languages, such as Common Lisp.

If I wanted to do this, I'd just write Elisp scripts that would be
invoked via shell scripts or something of that sort using Emacs' batch

An alternative would be to implement everything yourself from group up,
and follow up on the development whenever something changes.

Another one would be to extend something like tree sitter by Elisp

Not everything relating to Elisp development in implemented in C. You'd
also have to read the Elisp parts.

I don't know about that, but AFAIK the project has stalled.
