I own some Theta gear myself. They're pretty adamant about grounding their product. If you have any warranty work done in the future I think I'd leave out the ungrounded part when talking to them.
Where there is a will there is a way. I’ve been an Electrician for twenty years and I can pretty much guaranty you can get ground to that outlet one way or another.
While you’re at it you mine as well run a dedicated circuit or two.
Good luck :~)
PS- This is only my personal opinion. Normally I would agree with Bob but grounding is something I take very serious in my line of work.
