I'm completely ignorant about this matter, but why is it even possible to cut off fuel while taking off? Shouldn't there be a control that completely disables this? Is there actually a situation where cutting off both engines could be necessary and wouldn't lead to a catastrophe?

Engine fire requires you to cut fuel to the affected engine.

Is cutting off fuel while taking off a better solution than letting them burn?

Sometimes? If you have enough altitude to trade for speed then after the cutoff you could glide to a hypothetical miraculously-placed runway right in front of you, vs. having fire quickly consume the entire plane if you don't cutoff..

Pretty sure nearly all runbooks have you first move the thrust lever to idle before cutting off fuel. That suggests you shouldn't be able to cut fuel independently of the throttle.
