The Parseltongue statement must be a critical part of the upcoming solution, I think. Simply killing the Death Eaters will not do; they are, as Voldemort puts it, useless. (That is, a solution that disables the Death Eaters but not Voldemort is not a solution.)

The text of the boundary conditions suggests that Harry can't change Voldemort's values, but the lesson suggestion makes clear that he can change Voldemort's beliefs.

I think the first thing for Harry to suggest is that the prophecy is being misinterpreted. The trouble with this is he needs to hear the prophecy to argue it as well as possible, and Voldemort is unlikely to tell it to him.

So, what lessons does Harry have for Voldemort? Partial transfiguration, and implicitly timeless physics. Friendship? Science fiction? Dyson spheres? We, with knowledge of the prophecy, can feed Voldemort the data he needs to come to the right conclusion.

(During these discussions, of course, he can be partially transfiguring whatever he likes. Carbon nanotubes, hollowing out the ground beneath him, and so on.)

Harry can talk to LV about the life cycles of stars and the heat death of the universe. All this could force LV to rethink what it means to be immortal when the sun engulfs the earth or the universe hits maximum entropy. This could buy some time.
