No. One single hallucinated citation on a document with you as an author is not evidence of your reckless disregard for anything. These exaggerations are crazy and you would absolutely deny such accusations if you missed your co-author's AI hallucinating a citation on your manuscript too. At best it would be careless, if you really relish extrapolating from one data point and smearing people's character based on that. Not reckless. It's quite literally the difference between going five miles per hour over the speed limit versus fifty.
