I do think the first spell cast should be initiation. As a fighter, I don't have the ability to detect what sort of spell you're casting or are about to cast - it could be an instant death spell or it could be a buff, I'll never know - but also as a psychopathical Cyricist, I suspect everyone's out for my blood. Typically, you can tell when PK's about to happen based on conversations IC and, as always, there should be the OOC throw up of "Hey, we're about to throw down." which doesn't happen as often as it really should. Someone says, "I'm going to kill you." or draws their weapon at me or anything else like that, I take it as a sign of hostility. A priest/wizard's main weapon is their mouth, so when they start casting it's who knows what.
To reiterate, I do think the first cast is the first initiation.
However if that rule changes, you'll have people wandering about pre-buffed far more frequently than you already do which is another delicate topic of discussion for people.

I would imagine silence or web as examples.
In that instance? Yes, it's a hostile gesture, both in an attempt to overpower/overtake the enemy. Poor form if OOC discussion has not happened.
You'll shed your blood, your bodies fall. That is the price you'll pay to cleanse you of your sins. Vicious and cruel, let's kill them all.
Let's kill them all.
