Based on that text, I figure they would not drink milk or animal products, as that might be considered using them as a beast of burden. I can't imagine they use vilekin as their work animals, so they probably just hunt them occasionally, or potentially harvest them.
As far as clothing, plenty of clothing is made from plant fibers in this game, so you could argue that! Probably naturally gathered rather than farmed, so they wouldn't need animals.
