Eh, the stats don’t seem to support EVs being terribly explosion-prone either. In comparison to gas cars, maybe, but both are very safe in absolute terms. Harder to extinguish if they do catch fire, but I think if I came upon a fresh accident and there’s no immediate signs of a battery fire (airbags smoke, it’s normal), I would still leave the victim in the car seated until someone trained shows up.
Sure, be ready to get them out, and if they’re trapped and it’s going to be a while until fire shows up start working on that. But my mental model is that for any road legal car that is not currently on fire, there is a higher chance you’ll cause harm by rashly moving a victim than that a victim will be suddenly consumed by an enormous Hollywood style conflagration.
