“Finally, I would love to hear what a non-American possek will have to say about this as I tend to view the opinions from E”Y as not being tainted by the shmutz of golus. What would R’ Chaim say?”

” whether or not a Jew is permitted to give candy seems almost irrelevant to me.”
Then you are on the wrong thread. since that is the entire discussion at hand.
and Halacha should never be “irrelevant” Not ever.
