I'll try to answer these as best as I can.
i made my own (as i was connecting to an older 30A circuit for an older welder), but i've seen this one mentioned more than once for people who don't want to make their own:
https://www.amazon.com/BloomGrow-110V-120V-220V-Adapter/dp/B075FTC9RT
and close enough, considering the cost difference.
Lots of owners do this. Amazon sells various adapters for this purpose, including this one and this one.
I agree that it's off-label use, but there has been pretty significant research into it (see this album). It's also basically the same board that's in the Amazing-e (a UL-listed 240V charger), as shown in this video.
One thing that is abundantly clear is that the adapter is fairly explicitly designed for US-style 240V use. Specifically, it has a check-light for wiring faults, and it absolutely could check that there is negligible potential difference between “neutral” and ground. It does not, because adding such a check would break US 240-volt use (while still being fine in Europe on non-split-phase power).
It's not illegal, and I think if you somehow did burn your house down, it would probably be seen as no more negligent than various other kinds of foolishness that result in the same outcome.
