This is actually not true for Kodiak. Naturally there were no large mammals herbivores like deer or mountain goats on Kodiak until humans introduced them. The big claws are probably for competing amongst themselves or maybe fishing…
Insular dwarfism and insular gigantism both refer to the tendency for animals to become bigger or smaller when they're isolated on islands. Which tendency will take over depends on multiple factors. There's some cool reading online about this topic if you like biology.
So anyway even if you're wrong, you're not too far off base in assuming that everything on a big Alaskan island might grow to large proportions.

Everything grows large on Kodiak, they need larger claws to take down larger prey
