I agree that in my experience, AI image generation does generally still struggle a lot with generating nice simplistic graphics relevant for these types of uses. However, I think the idea of having a large enough catalogue of graphics, pictograms, and backgrounds that an "AI" could choose from based on the instructions would give a much more customized experience.
