Shiva not being able to destroy it doesn't mean much about how strong Trihexa is in comparison to Great Red or Ophis individually. He's not able to destroy Trihexa, but it's implied that he can fight it. If Shiva can fight it, then Great Red or Ophis, who are stronger than Shiva, are individually at least on par with Trihexa.
