UL certification is a requirement for an electric or electronic product to be licensed for sale to consumers in the US. This is enforced on US manufacturers of a product and on importers.
Whilst people buying something from AliExpress for personal use and importing it themselves don’t have to obbey such requirements, those importing them or making them for sale in the US do.
The CE mark does the same thing in the EU.
No idea if in the US there are further licensing requirements for things to be connected to the grid that would close the importing for personal use loophole.

That is completely incorrect. I own a ton of equipment that is not UL listed.
Further, UL listed equipment is not prevented from backfeeding to the grid, and in fact most of it is intended for precisely that.

In the United States that would be UL Certification.
UL is not a license. It’s a certification. And you forgot the second question.

There aren’t.
You are correct.
A little digging shows that unlike the CE mark in the EU for electronics, “UL certification isn’t mandatory, but may be required when selling electronic items to retailers”.
