The "server" in "language server" does not mean "server you access over the network" but "other process (on your machine) your editor talks to". (This is just the spec for a protocol.)

Can it be on across the internet? So, Apple can or cannot set up an internet service for Swift? If I think I have a better version can I point my editor towards that? If I program in a couple of languages, do I need to get ahold of servers to install?

  To answer your points in order: No reason it couldn't talk across the Internet, I guess, if you're comfortable sending your source code to whoever is running the server and dealing with network latency on your autocomplete. Yes, you could easily point your editor to a different server, this protocol is basically just an API spec. And lastly, yes, you would (likely) need a different server for each of your languages - this project just provides a way to let an IDE implement one API client that can be used with each different language's tools.

I'm thinking as part of a remote learning class. I'm pretty comfortable that it wouldn't violate any student privacy rules.

Each language would, in theory, provide its own server to do analysis. Of course, your favorite IDE would likely be more than happy to start the server for you if it's not running yet (as it's just a small process that runs in the background). If you want to see how this works in practice just grab Visual Studio Code and start editing a Typescript file. This is already in use there.
