I will keep it in mind, though a quick search returned a project that resemble LSP integration for Ruby : https://github.com/Shopify/ruby-lsp.

Also RubyMine (IDE from Jetbrains) seems to have its own LSP integrated.

There are some limitations with ruby-lsp. I'd recommend checking some sources to identify if any would be a dealbreaker.
