The suggestions below *MAY* work [no guarantees whatsoever]

You may try to select different "pseudo smart host" based (e.g.) on
envelope sender or authentication credentials used during local
submission. "Pseudo smart hosts" will be a CNAME to smtp.gmail.com in
your local DNS domain (BTW smtp.gmail.com is a CNAME). You may create
one wild-card CNAME *.gmail.smtp.example.com for all pseudo smart hosts.
It should allow you to specify different outgoing AUTH per "pseudo smart
host".

In case of problems with connections caching use custom mailer
(variation of esmtp mailer) for smart hosts sending one message per
connection.

Relay selection based on envelope sender had been implemented in
(discontinued) smarttable. It has been never supported by sendmail.org.

P.S.
"Right way" would require changes in sendmail source code:
* selecting outgoing authentication credentials based on more data
* caching of outgoing connections

BTW It will be better in sendmail X, will not it? ;-)
