So, in Vuen's Tomb, the AI has the ability to cast CTA WELL beyond it's Line of Sight and into my Training Room/Dungeon Heart. This means I am in no position to fight the AI Keeper while fending off Hero Waves.

This has always been the case. Even in the original dungeon keeper the enemy could cast CTA anywhere.
And I don't really think this is something worth changing. Sure, a human can't do it, but the creatures still have to walk all the way and explore. So as a human you could just cast cta on the edge of what you explored, recast it several times until you are where you are. I don't think the AI gets an advantage with his behavior over the human player, if anything it's a disadvantage because units get fewer chances to regroup.
Also, see the topic about that map, and I believe this is the intended behavior.
