That is going to be between you and your local AHJ.
It does not say things have to be listed in 110.2 only that they are approved. Your AHJ can pretty much approve anything he wants but listing by a NRTL is a handy/safe way to make that decision. By a like token they could disapprove a listed product. Issues surrounding the Purple Ideal 65 wire nut spring to mind. There are a few AHJs who believe CPSC over U/L on that and will not accept aluminum/copper splices with them.
ZMVV in the white book does not talk about twisting the wires in any way. It defers to the manufacturer's instructions. Most I have read say "it is not necessary to twist the wires" but it doesn't say you can't.
