I have not tried this one, but the predecessor (typst-lsp) was working fine with Neovim for me when I did my little Typst experiment last year. Whatever the VSCode plugin is offering should be possible to replicate on top of tinymist.

Tinymist is working very well with Neovim too - and there is a preview plugin based off of tinymist, too, for Neovim.
