Doesn't look like ground lift to me.
I clearly see a pin in the clear part of the plug and see no metal tab like most ground lift plugs have. The clear part im assuming you think is the ground lift is actually the male end of the 30-15 adapter plug.
Unless im missing something??
Everything you showed looked like normal adapters.
Here's a ground lift plug
Looks like a legal and grounded connection to me. They are only running the LED lights and maybe a fan at a show. Depending on the venue, most require a in house licensed electrician for any electrical connection. $$$

They opened the fridge cover on the trailer behind and had a ground lift in there. Most Trailer are daisy chained and wires running under carpets. Guy was not liking pictures.
