They don't produce enzyme 42. The fact that they don't emit it out of their bodies doesn't mean that it would be impossible to obtain. If other Leviathans were capable of producing enzyme 42 the precursors wouldn't have doomed their whole species by only researching Sea Emperors. They would have just caught a couple of Sea Treaders or something and bred or cloned them and extracted enzyme 42 surgically.
