start lsp server alone

[rogercloud]

I see that lem is implementing the LSP functions. Can I run the LSP server alone without starting lem? If yes, how can I do it?

I'm not sure what you're talking about. But Lem implements the connection to the LSP server but is not an LSP server itself. If you want to use an LSP server, you can use one for Python (pyls, pyright, ...) or for Rust (rust-analyzer, ...) or something else.

You can consult the LSP documentation for more information on how they work: https://microsoft.github.io/language-server-protocol/
