It pisses me off. I’m going to spin a Bitcoin and Lightning node back up on Umbrel and move things that way. The node on AlbyHub is apparently not reachable without any channels open. I’m fairly sure it is by design and they are getting kick backs from the LSP’s; I just can’t prove it.

If the node can be reached depends solely on your networking. You need to have the lightning port 9735 open and a publicly accessible address.
This is independent of lightning channels.
It's the same with LND or CLN. And you will have this problem on Umbrel if it is not publicly available on a public address.
that's just networking and independent of the app.
If you don't have the node running on the public network you can also open a connection to the channel partner's node first then the other node can open a channel without the public address.
