You clearly misunderstand. You cite a work in your paper because you have read that work, and build upon it or want to refer to it to back up a specific claim. Generating references is fraud period, because you are implying that you have read a work when in fact you just asked an AI "please insert some reference-shaped text here" to make it look like a proper paper. It is sadly not a necessary, but certainly a VERY sufficient, reason to conclude a paper is fraudulent.
