Shiva couldn't fight toe-to-toe with Trihexa, not at all. The thing about the 3 Dragons in the first place of the Strongest Beings in the DxD universe, is that they just leave everyone on the second place in dust. Those in the second place cannot come anywhere near the ones in the first place. Heck, even all the top 10 gathered wouldn't be able to do anything to anyone from the first place.

So, no, Shiva is not toe-to-toe with Trihexa. He was asked by Azazel to destroy Trihexa, because Shiva is indeed the God of Destruction, but Shiva didn't destroy Trihexa in the end, saying he can't do it, because Trihexa is way too strong for him alone to handle.
