This isn't "a style", it's a badly designed encounter that fails to inform the player in advance of what it is going to require of them, of the kind that the old Baldur's Gate games don't have. The old Baldur's Gate games don't instakill you for rolling one bad dice in a conversation because they thought of a funny scene, they have hard encounters and even impossible encounters that can come as a consequence of player action but you have to actually take volitional actions in free play to engage them.
