Just bentonite is fine. Yes, cover the outlets adapter with bentonite. That has been a concern of Washington's Dept of Health in our Technical Advisory Board meetings. They have seen instances where the spud nut on the pitless adapter wasn't tightened enough or a sloppy hole was cut, resulting in surface water leaking into the well around the pitless adapter.
A correctly drilled hole along with a correctly tightened spud nut should result in a sealed fitting that will hold pressure from the inside or outside.
As a practical matter, probably less than 5 percent of wells have the surface seal restored after digging the trench and installing the pitless adapter.
