The TLS handshake/setup only happens after a successful TCP connect, so
that is very unlikely.

Or to put it another way, before computers on a network can start
agreeing on talking encrypted to each other, they have to agree on
talking together in the first place. In this case one of the computers
(gmail) says "go away" the moment the other computer tries to talk to it.
