GenAI CAN do that, but it also can regenerate training sources as-is. The way LLMs work makes it quite likely that once it has started copying a training sample it will continue to do so (after copying/generating N consecutive words of a training sample, the most statistically likely next word will be often be the N+1th word of that same sample).
The same thing happens for images - the more an output looks like an input, the more likely (as diffusion-based generation proceeds) it is to look more like it. There are recent examples of Dune posters being recreated essentially as-is.
