He does not need to add another layer of insecurity to his system such
as sudo. Not saying that this is bad but it feels like a little overkill
for something as simple as this.

This can be done old-school.

pw groupadd _zfsadm
pw groupmod _zfsadm -m {username}
chmod u+s,o-rx /sbin/zpool
chown :_zfsadm /sbin/zpool

Repeat command line 2 for every user you want to have root type access
to /sbin/zpool.

Of course you do not need the zfsadm group to do this. You could just
use the wheel group which in turn gives any member of that group su(1)
access to the root user, so you commands would turn into...

pw groupmod wheel -m {username}
chmod u+s,o-rx /sbin/zpool

Because this binary is already installed group wheel there is no need to
chown it. And this is a little more implicit that you trust anyone with
access to the zpool command will also be having access to su(1)

Pick one, and Ill leave the "how to keep these permissions through
upgrades/updates of world" up to you.

Good luck & regards,
