Not sure about lsp, but I think if you defined your language in tree sitter, you might be able to define a basic autoformatter generically on tree sitter to accelerate bootstrapping your language.

You could also use an existing language agnostic package manager like nix, guix, or conda to bootstrap your language package manager.

Lsp is something I don't know of a way to make that easy without overly constraining the design space.
