I haven't listened to the podcast you mention, but the answer to your question is yes. Quoting the langserver.org homepage[0]:
> The Language Server protocol is used between a tool (the client) and a language smartness provider (the server) to integrate features like auto complete, go to definition, find all references and alike into the tool
In LSP terms, these are called "capabilities". The relevant section in the LSP spec is here [1].
There's some variation across editors in exactly how the config works - or, at least, part of it. Some config is done in native files that form part of the plugin. Those are largely editor-specific. The protocol itself defines messages for the server to indicate which facilities it supports. Those are (mostly) editor neutral from my experience thus far (mostly VSCode, a little Emacs).

Yes, the genius of LSP is that it doesn't attempt to define common semantic operations across languages, which would be (and has been) an endless impossible task to get right. It operates at the level of editor UI. So you don’t ask LSP “what are the members of this struct”, you ask it “what are the autocompletions of this code fragment”. It leaves the decisions about what would be appropriate in the language to the language server written by the experts in the language.
