Why do you need to eval it?

$(ssh-agent)

won’t substitute that with the stdout and run that?

Because the intended use for "ssh-agent -k" is for eval.

While redirecting to /dev/null will certainly work, the agent is holding sensitive credentials (by design), and confirmation of shutdown has a tangible security benefit.
