Was that the exact message you got? Never seen this message before, it sounds a little funny, but you have nothing to worry about because as you say the item is authentic. Worst that could happen is the listing gets flagged and removed, if they do "refer your listing to the company or law enforcement" you have nothing to worry about in that case.
And you won't get suspended for one listing violation, you'd probably get suspended for 7 days, but it usually takes a minimum of three to get suspended indefinitely. Just remember to use a lot of detailed pictures and whatever else you can provide in the listing to prove authenticity.
