No need to actually play out the combat. You said you want the Elysium Titan to win, so it wins.
Possibly you can't get the Balor's stats due to the misspelling?
I'd focus more on what cool and dramatic things could happen in such a fight, and most importantly, how they could directly provide excitement for the players.
Does one or other get thrown and nearly land on a player? Does one of their powers or attacks miss and destroy a structure or section of landscape? Does one focus on the players for a round before being distracted by an attack from the other?
And of course, when the Titan eventually kills the Balor, what do the players/Titan do in the face of it's death throes?
(Balors explode when they die. As a player, I friggin' hate monsters that explode when they die (lost two characters to exploding balors) but as a
GM I freakin' love the drama (nearly crippled the parties airship with an exploding Frost Wyrm in one campaign

)
