I'm mounting a new meter can and running 4/0 through the knock-out in the
back of the can and directly inside through an 18" brick wall. Do I need
anything like a knock-out plug for the back of the box or can I just run
the wire through the knock-out hole.

If anything, I'd be worried about water getting back down through that hole.

thanks,

If your running service entrance cable you need service entrance cable
connectors, if your using PVC, you need PVC connectors. You never just run
cables or conductors through an open knockout, Especially into an unfused
meter pan

Where I live, because this is the electrical service you would need to
install a metal nipple between the meter can and the panel inside, along
with the bond bushings.

Every jurisdiction and utility are slightly different from locality to
locality. Get a local pro to point you in the correct direction.
