"While hallucinations are reduced relative to general-purpose chatbots (GPT-4), we find that the AI research tools made by LexisNexis (Lexis+ AI) and Thomson Reuters (Westlaw AI-Assisted Research and Ask Practical Law AI) each hallucinate between 17% and 33% of the time."

However, as also elaborated in the paper, the issue is not merely about providing wrong (including nonexistent) references but also about factual correctness of the references or not giving references when needed.
I don't know whether these and other aspects of Perplexity's (or CoPilot's) references have been evaluated.
