You might find the invocation scripts in /etc/bashrc, /etc/profile, or /etc/profile.d/*, which are general to all users on the host. In principle, the agent should die when you log out, but I've seen some folks out in Google land add explicit kills to .bash_logout.

In any case, gpg-agent processes with a parent PID of 1 have been abandoned and can be killed. Any /tmp/gpg-* directory older than the last time you logged out can be deleted.
