I assume you don't literally mean "google.com", since they support
TLS, and you can just enforce TLS to "google.com" for both and be
done.
For domains where you're less certain of ongoing TLS support, you
can try to deal with this by choosing different transports for
mail from sender1 vs. mail from sender2, via
sender_default_transport_maps. In sender1's instance of the
smtp(8) transport, the TLS policy will be mandatory for
"example.com" recipients, while in sender2'd instance of
the smtp(8) transport it will be opportunistic.
