You could do a reverse proxy to your hidden service and making it available on the clearnet. You need a subdomain that points to the VPS and on the VapS you run TOR and a reverse proxy. Or you can look into Nostr wallet connect to connect a public LNbits instance to your own node, you would use NWC as a funding source for the LNbits I stand that runs on the VPS, or you add PhoenixD to the same VPS.
