I'd share a couple of perspectives with you on that, but then by now I doubt your sincerity in this discussion.
Vitale is ok on techniques, practical applications etc. His major LOA contribution lies in bringing the traditional Hawaiian LOA methods (known as ho'oponopono) to a more general audience.
But on the kind of questions you raised, the better sources are Abraham Hicks; and Ramtha; or the earlier books of Gary Zukav (eg "The Seat of the Soul"). Or even Buddhism.
If you are intuitive enough, you'll glean insights on these sorts of questions from non-LOA sources like Brian Weiss and Raymond Moody.
The argument that "Starving children wouldn't attract starvation to themselves. The fact that there ARE starving children shows that LOA is false ...."
is essentially a similar argument to:
"If God exists and is good, He wouldn't let any children starve. The fact that there are starving children proves that God does not exist, or that God is bad."
which in turn is a cousin of the following argument:
"Bad things should not happen to good people"
which is a logical error known as the
just-world fallacy, of which you are a victim.
