No, pretty much all serine hydrolases are affected by organophosphates (assuming they can reach the active site). For example, the compounds IDFP[0] and MAFP[1] can both be used to inhibit serine hydrolase activity in vitro. Diisopropyl fluorophosphate can also be used, although that one actually is pretty much a nerve agent (it's volatile).

The only reason the wholesale disruption of hydrolases is not the thing that kills you with nerve agents is that acetylcholinesterase is particularly susceptible to organophosphates (wide open active site) and essential to nerve signal conduction. Thus although sarin (for example) will wreck most hydrolases in your body, this won't really matter when you'll be dead in a few minutes from your nervous system being unable to tell your lungs to breathe.
