Hello.

Dromlexer's answer could work. Synthetic lab grown meat is one possible solution. And really, as cyborgs, you can't rule out that they aren't using minerals and likely organic compounds to synthetically produce sustenance.

But I'm going to take your question at face value and show how it reduces to absurdity. It assumes from the onset they have nothing to eat, despite the premise of the question being about what they could possibly eat.

Lets stay stringently true to the point Grox are carnivores, and Grox turn once flourishing planet into uninhabitable one. By this I assume you mean they extinguish all life not themselves. Thus a and b implies c: that the Grox are carnivores that have nothing to eat.

Now I'll go back to the first point. Why can't the Grox absorb nutrients from other sources? Sorry, but the only way out of this trap is to reject the premise and admit more language. Maybe the Grox were once  carnivores and now choose to absorb nutrients; or maybe they produce synthetic animals from aforementioned nutrients. And why can't a problem solving technological culture engineer themselves to do this without a a well defined reason?

I hope you can see its a lot more fun to think in this way.
