Does anybody know of a PPE supplier that has an LV rated glove with a documented ATPV rating?

Oberon and Salisbury/Honeywell are two. Just do a search for arc rated glove and the will come up.

NFPA 70E 130.7(C)(10)(d) Hand Protection permits heavy-duty leather gloves or arc-rated gloves (a footnote provides additional info)

The ASTM standard is ASTM 2675 and we have an IEC standard for arc rated gloves that is in development as well.

When you mention "LV gloves" I'm assuming you're referring to leather protector "gloves" that are specifically designed to be worn over rubber insulating gloves per ASTM F696?

If so, then my company struggled with this same dilemma because all our class 0 and class 2 leather protectors from Kunz and Salisbury did not have an ATPV rating nor were they tested for arc flash protection. Then we discovered a company by the name of Youngstown Glove company that makes leather protectors with an ATPV rating per ASTM F2675 for our class 0 and class 2 rubber gloves.

They even sent us several samples of their leather protectors to try out during our evaluation of the product.

And this investment paid off for us back in March 2021 when we had a significant arc flash event in a 480-volt MCC involving one of our contract electricians. While there were many human performance errors that lead up to the event which I won't get into here, but the one fact that prevented any injuries was the individual involved was wearing arc flash and electric shock PPEs, including Salisbury class 0 rubber insulating gloves with the Youngstown leather protectors with an APTV of 36 cal/cm2 worn over them.

The MCC involved has an estimated calculated IE of approximately 3 cal/cm2 @ a working distance of 18". However, the electrician's hands were less than an inch from the arc flash itself, coupled with the fact the upstream breaker never tripped open, so his hands were exposed to much greater IE levels than the calculated IE. As you can guess the leather protectors took the brunt of the hit which caused significant damage to its exterior parts, especially of the fingers, palm and back of palm. However, none of the stitching burned open and a visual inspection of the interior portions of the fingers and palm areas indicated no signs of heat transfer through the yellow Kevlar fabric used to line the inside of the protector. The portions of the rubber glove itself covered by the leather protector also did not show any signs of heat exposure but the same can't be said of the exposed parts of the rubber gloves. This real-world test of the Youngstown leather protectors, albeit unexpectedly, has given us much confidence in selecting this product for the protection of our employees and contractors.

The Youngstown glove company makes a few styles of leather protectors with different ATPV ratings.
