HI Adam! I agree that the reason they are using digital is it's a lot easier to use to teach classes with, record make edits and present with - there is nothing "wrong" with working traditionally. I went to art school for animation/illustration and I didn't learn digital until about year 3 out of 5. We had a few visiting pros who used digital mediums and gave us tips. But the idea was that as long as you understood how to make art traditionally, you could then translate that knowledge to any other meidum. It was FOR SURE a learning curve to learn digital eventually, but easier since I wasn't learning digital and foundation skills together. Also, if you're into Children's Illustration, there is still a desire for traditional work, so I think you'd be fine!
