Getting hit by a sword swung by an NPC isn't telling the player "you decide not to dodge". It's narrating the outcome of an action declaration.
And as far as I'm concerned "You find the person's arguments convincing" is, too.
Telling the player "you believe the NPC" is, indirectly, telling them what action declarations to take in the future. (And if it isn't doing so, then what's the point of saying it?)
See my posts above. There are ways to set that up where they can at least put their thumb on that scale so they're not out of the loop that don't provide them unlimited immunity to this sort of thing. If that's not satisfactory, its not, but I'm not going to indulge in the assumption that its got to be all-or-nothing.
