Yes there is. Nidalee's bushwhack does armor reduction.

Also, I think the info from your post is not correct. Armor reduction comes before penetration, and it can drop armor below 0. But penentration will never go under 0 (or will not decrease it further, if a negative armor was achieved by reduction)
