Would you be comfortable playing online vs. someone you knew had GTOWizard open on his second monitor, but promised to only look up spots after hands were over?
Probably first need to define "comfortable." In my case, I'm such a rec that even an opponent who last consulted a solver two weeks ago would scare me. It tells me knows his ****. Overall, I'd feel more "comfortable" facing someone for whom GTO means "that car my dad drove in the 1960s."
But to answer your question more seriously...
In practice? No. The problem with this scenario is that you can't really trust that the someone is doing what he promises to do.
Now, suppose he's playing on camera with his main screen visible, like a Twitch streamer does. And suppose also that he has his solver display behind him, such that you know exactly when he's looking up hands. And on top of that, the second monitor is such that you can see it, ensuring that the hand he's looking up is NOT the one currently running. Furthermore, you two have entered into an iron-clad agreement that you won't rat him out for using RTA, especially since you'll have solid evidence to that fact.
Under all of those circumstances, sure... I would have no big problem with it, especially if I was allowed to do the same.
