You can’t send packets except to the captive portal before you sign in to the network. That’s how captive portals work. Only after signing in can you then reach other servers, probably including your own.

As far as security concerns about sketchy VPN services, you can at least control your connection with openvpn.
Use tls-crypt to encrypt your initial connection.
Don’t use public Wi-Fi for anything sensitive regardless of your confidence.
