Wikipedia has the resources to combat it. You would be the main contributor to the wiki. If even you don’t see the problems with unchecked and unsourced AI content, the thing is cursed from the beginning.
Again, if the AI correctly copied and summarized the contents from the sources, the person who wants the add the content to the encyclopedia should have no trouble finding it, checking its accuracy and adding the source. Then it is no longer AI generated, but checked and correctly sourced.
