LHOs are arguably the most official and responsible people in MD. They have a very special status and are tasked with helping and knowing. Part of helping, is knowing. Even though I have played MD for years, I would still expect an LHO to be able to support me where my gaps are - and if they werent 100%? to say so or find out. I think it's cheapening them to add that caveat, not to mention alleviating them of what is, imo, part of what they are there for. If an LHO gives a player advice, it should be right or they shouldnt be giving it - otherwise they might as well not be LHOs.
