I heard that Android VPNs can have some sort of fail-closed mode, does
this apply to Orbot?

But the Android device isn't a gateway, unless you're tethering? If you
mean only applications with native Tor support should be let through,
that's the "access:fenced" option. Setting it up for all of the main
device user account is literally that as one line, "access:fenced". Or
for just a specific app, it's "access:fenced app:com.example.foo":

I don't see any security problems per se with transtorifying *on the
device that's generating the traffic*? (Transtorifying *other client
devices* is problematic, for sure.)
