Well yes, automation makes a massive difference because with a machine you can crank hundreds of panels in a particular style in the time it takes a human artist to do a single one.
In fact, I generated a bunch of Tintin panels between writing my earlier comment and this one, and they're bad but not terrible - mainly because I asked for 'Tintin riding a bicycle [...]' and it's having trouble with things like the bicycle spokes. Two out of the 4 'feel' right in terms of the line drawing style, color palette, foreground-background composition, level of background detail etc.
