Pyright is billed as a "static type checker" but its a full-blown language server (which pylance is built on). I've used both pylance and pyright and frankly I haven't seen any benefit going up to pylance. Pyright is under the MIT license so it can be used for anything: https://github.com/microsoft/pyright/blob/main/LICENSE.txt

I use Pyright as my LSP in Neovim and I’m very pleased with it.
