I doubt that anyone in RNJR knows how to make antivenom reliably, so their best chance might be to steal some off of Tyrian if he has some.

His venom seems to act as a blood thinner (at least so far), and that seems like a hard venom to use in a nonlethal capacity without having an antivenom, particularly since the delivery causes wounds. Granted anything in sufficient quantities can be fatal, but this seems to be a more lethal poison and he had been given a capture mission.

Alternatively they could somehow get help from a person who knows how to make antivenom and to keep Qrow away from the booze for a while.
