With a VPN, the only real attack vector here is to block the VPN traffic and hope the user disables it or doesn’t notice it didn’t connect. No modern VPN will handshake with a spoofed server so it will just never connect. In some cases, the connection might fail silently enough to fool someone like this, but basically every mainstream app these days is pretty vocal about that for exactly this reason. As of Android 13, the default behavior is never to pass traffic outside the VPN unless the user explicitly turns it off. On other platforms this is dependent on the specific app.
