Point taken.  Being "only" Lactose Intolerant makes some things easier.  
I mention Lactobacillus because many people have GI problems while 
taking antibiotics and can be helped by it.

Having said that, I use Nature's Bounty Chewable - which does NOT seem 
to have any milk products at all - see

Ingredients
Sucrose, Dextrose, Fructose, Citric Acid, Strawberry Flavor (Natural), 
Vegetable Oil (Palm Olein, Soy, Coconut, High Oleic Sunflower Oils), 
Vegetable Magnesium Stearate, Silica

Maybe that's an alternative?
