If it's a ranged power requiring an attack roll, he picks a square and takes a -5. If it's a close or area power requiring an attack roll, he picks a square and doesn't take a -5. If it's a utility power that has a target but no attack roll, he picks a square. And if it's a power that affects an ally without designating him a target, it's automatic.
About the only powers that automatically fail due to broken line of sight are ones that say something like "Each ally in the burst you can see".

I thought los was required for forced movement.
