I'm confident it's not yet economical for them to do that, as even the entirety of official TSR and WotC art would not be enough to train an effective AI, specifically since so much of the art they have, and need, is for weird fantastical creatures, which AI art generally struggles to produce useful results for. Try getting an AI to make a mythical creature (other than unicorns, they're good at those) and you'll see the problem. If the art for various D&D things had been more consistently "on model" over the decades it might be a somewhat different case, but it's still not enough data points for current AI.How does it benefit them to stigmatize AI art when you call them out specifically for having a vast trove of art they own and paid for to train an AI on completely legitimately if they wanted?
In ten or twenty years, when the tech is better and their art has followed a somewhat consistent house style for longer there might be more sense in WotC training their own AI for some of their art. And by then their less well-heeled competitors will have normalized the use of AI-assisted art. Right now the market favors them continuing to use their position to outspend competitors on traditional art.
