Thanks, so you've now explained the problem and said the magic words 'OpenVPN'
which means we know where we are.  That's an 'OpenVPN client' and so these
instructions apply:
https://openwrt.org/docs/guide-user/services/vpn/openvpn/client

I'm assuming you're paying somebody for an OpenVPN server on the internet
somewhere?  Rather than running your own server on a cloud server somewhere?

There's nothing special about an RPi if you're running OpenWRT, it's just
another OpenWRT box.  Don't try and hack around your system with scripts
designed for running on other OSes on a Pi - it's all already integrated
into OpenWRT.

The main thing is the Pi has no hardware crypto acceleration so your
performance might be limited by the Pi 4's CPU.  Probably not an issue
unless you're pushing hundreds of Mbps.
