The Illustration programme at ARU is closely linked to their Animation programme - as well as the joint course, they tend to have a fair number from one taking options from the other, to my understanding. I think they actually have a shared first year. Thus, there is still a fair amount of digital content in that.
There are options to cater to a variety of interests and styles - as I recall the illustration/animation students had a very broad array in their final degree show when I went to my sister's one. Some did stop motion, others did 3D, some did traditional animation and others did more unusual things (rotoscoping, stop motion style cutout/shadow animations) on the animation side, and on the illustration side there was a great variety - from western comic style, to manga style (by far the worst pieces in all cases, incidentally) and e.g. childrens book animation styles (with/without "dark edgy" twists, depending on the student).
I know one of the Illustration/Animation students got a job at Aardman Animation a few years after graduating, although she's now left that to do a PhD somewhere else. I got the impression the joint course was slightly more skewed to animation in some sense, perhaps just because it's inherently more time consuming so students ended up overestimating and spending more time on those aspects of the course. But the main point is, I don't think I'd suggest it's particularly "traditionally" oriented - it just has that as one of several options available. There are a great number of art/design based courses at ARU, and they tend to intermingle a great deal, so there's quite a strong sense of an "arts" community there.
