jeep snorkels are for air intakes for engines. electric cars don't have air intakes. they have air cooling for batteries... I suppose you could snorkel those.
A decent welder should be able to turn out a trailer hitch <=> outboard motor bracket in under 15 minutes. It's not like you'll need much more than a modest fishing outboard to get through flooded spots.
You'd need to ensure every electrical connection is in a waterproof location which I'm pretty sure is not a thing for any standard car manufacturing. Cabins are also rarely watertight.
AFAIK your best bet is a diesel with a snorkel, and hope things have dried off before you need to restart the engine.
That's...the joke. The humor is in the absurdity of recommending an addon to the car that utterly would not work and would look ridiculous. It's layered on the fact that Jeep snorkels look sort of ridiculous even on the vehicles they were designed for.
