If your a practicing attorney and you think there is malpractice or unauthorized practice of law you HAVE to report it according to the Illinois Rules of Professional Conduct. You can be penalized by the ARDC for failure to report of there is actual misconduct. Honestly, it doesn't hurt to turn in the information you know. It covers your professional obligations and puts the ARDC on notice to deal with the situation as they deem necessary.
From the facts you've given, I can't say that there really is any misconduct. It is common practice and completely acceptable for non-attorneys to prepare documents and complete legal research under the supervision of an attorney who reviews and signs off on the document, thus taking responsibility for it. But, it's better to err on the safe side, for you, to report it. If the ARDC finds no issue with their conduct, then no harm has been done.
