The idea of an ELisp LSP server has been mentioned back when ELisp LSP
clients (lsp-mode and eglot) got off the ground.
I don't know of anyone having attempted to implement it, tho.

I don't understand what kind of answer you're looking for.
AFAIK most of the pieces are readily available in Emacs itself.
So I'd expect it's largely an effort of integrating those pieces (but
there's probably a fair bit of code missing to implement the server
part of the LSP protocol).

I'd expect an ELisp LSP server would be written 100% in ELisp.
