Indeed. It seems to be a situation which is hypothetical (i.e. highly unlikely to arise) as well as based on a misconception.
As for the qualms: monks sometimes talk about that in the Dhamma talks they give. I've recently heard one say, in regard to saving people, that a monk's duty isn't to save people, his duty is just not to kill them.
Quite possibly. When I attend the local monastery and listen to a dhamma talk, I'm not expecting to be saved. If I had that expectation, and the monks had led me to believe that they were there to save me, I might be upset when I heard that. But as I have never expected monk-borne salvation, I'm perfectly OK with the situation.
But you don't have to trust just any of those people with your life.
In contrast, when accepting a monk's exposition of the Dhamma, you put your life in his hands.
Lay supporters working with monks in the forest might put their lives in the hands of monks - they use some fairly dangerous machinery like chainsaws, chippers, and tractors. But when I accept a monk's exposition of the dhamma, I'm just looking to pick up some advice on how to improve my practice. Stuff like how to meditate better, more useful textual exegesis, reminders about how to stay calm when driving. Nothing they say is going to kill me, or save me from imminent death. (Mind you, they are more likely to give me instant psycho-physical salvation than an intelligible explanation of Dependent Origination...
You seem to be labouring under some assumptions about monastics that I (and the monastics I know) just don't share. Have you actually met any monks? Did they ask you to do anything that was tantamount to putting your life in their hands? And if they did, why didn't you feel free to discount what they said?
