Has anyone heard of an inspector asking for a UL listing for a ground lug in an enclosure to be listed for outdoor use? Dose this even exist? None of the manufacturers have heard of this either.

Ask the inspection if he wants circuit breakers listed for outdoor or wet location also. IMO, the inspector is barking up the wrong tree.

Just use lugs rated for direct burial, they are available we use them for PV system grounding.

Generally grounding lugs that are for wet or damp locations will have brass, coper, or stainless steel screws and hardware, the ones designed for dry locations are many times just steel screws and after a few months turn to rust.
I agree that the NEC is very benign on the subject other then requiring them to be listed for the purpose or listed for direct soil burial or concrete encasement and for the type of material the rod is made of (250.70), but I can also understand that after going back a few years later to see that the connection has failed because the regular steel screws had rusted through, most of our supply houses only have DB listed clamps or acorns which are also rated for wet locations.
UL white book might have more to say about it?
