have you considered https://openwrt.org/docs/guide-user/services/vpn/openvpn/client#commercial_provider ?

Start by configuring OpenWrt on the Pi for regular lan->wan routing. Since there is only one Ethernet port you will need to use wifi for the wan side. Add a network interface named wan of protocol DHCP client and connect a wifi client configured to connect to your wifi network. At this point anything connected to the Ethernet port should have regular non-VPN Internet access through the Pi. Then follow the standard guides to install a "whole house" VPN client.

If you configure the firewall with a separate zone for the VPN and then intentionally break non VPN lan->wan forwarding, the lan clients will have no Internet unless the VPN is working-- the so called "kill switch."
