I'm going to say "no."
Out of 31 solos that I see listed on JoJo's Wiki page, 0 have been acro. (This includes solos from Dance Moms, and from before the show outside television).
I see another 23 duets/group dances, and again 0 have been acro.
And she had another 1 solo and 13 duet/trio/groups on Abby's Ultimate Dance Competition, and 0 of those were acro.
