could you not ask the people on the milk allergy website? maybe they would have a better insight - i, personally, do not have a milk allergy, so i have zero knowledge about what products are safe for your milk allergy. apparently, the 600-800 people who frequent this site at all times don't know either, or you would have an overabundance of answers. you're asking the 'apple' web forum what they know about 'oranges' - we know a little, i suppose, as it relates to celiac but not all and not as much as you do. you have done a bunch of research, evidently, maybe you should share it with people it would help, like milk allergy sufferers?
if you were my kid, i would tell you to just take it. you'll find out but you are not. use your best judgement
