Your quote says “without any creative input or intervention from a human author”. Just hitting a "Generate random artwork" button indeed certainly doesn't seem to qualify as "creative output or intervention", but as for how DALL-E and consorts currently work, I'd say that coming up with a suitable prompt text, potentially refining it to get the output closer to what you want, curating the output, maybe using one of the output pictures as input for further processing, etc. arguably all are at least some amount "creative input or intervention from a human author".
