I can't find Patrick Wardle claiming that Apple apps aren't routed through the VPN. This claim was made my "Maxwell", but they didn't provide any proof.
Some VPNs were using kexts before Big Sur, some weren't. Wireguard for example is a normal AppStore app which integrates with the OS VPN support. It would suck to be confirmed that it's leaking traffic.
For what it's worth, a VPN will not protect you from threats on a hostile network.
