The ideal for me as a flow-seeker is the quick-edit feature of Void and presumably other editors. It saves me the context switching to google or docs to find the right syntax and method names for what I want to express, without requiring I waste my time waiting for the LLM to figure out what I already know (the what and the where).

The auto complete provided by your lsp server to your editor does a much better job of this than LLM's do, in my opinion.

My LLM-powered autocomplete can guess complete functions within 80-95% correctness.

No LSP server autocomplete has managed to do that.
