Eye dominance with a bow is (in my opinion) largely a non-issue. If you're shooting with both eyes open, and you're focused on the target (as opposed to your point) the all of this is pretty low on the list of things that matter.
If you were hard focused on the point as an aiming reference and using the eye opposite of your hand, sure, I can see it being a problem. But the reality is a bow isn't a handgun, and we don't aim them in the same way. In all of our pistol classes in the last 8-ish years, I've only ever had one shooter where I had them swap hands because of eye dominance. It happens, but is rare.
With a new shooter, fun is the first factor. Then form. I understand wanting to set them up for success, but good form will supercede eye dominance .
I say all of this as a right handed shooter who is left eye dominant.
