In my opinion, "Last name First name" redirects are necessary because as Callofduty4 said, people tend to recognize the characters' last names more than their first names. The most important thing about redirects is you get what you want automatically from the search bar, as the result sole family/first name redirect is completely unnecessary because yeah, you don't need to make an "Izuku" redirect for "Izuku Midoriya" because his name will automatically pop out. To summarize it:
 * "Midoriya Izuku" redirect for "Izuku Midoriya" ✓
 * "Izuku" or "Midoriya" redirect for "Izuku Midoriya" ❌

For the disambiguation, I don't think it's necessary. I handle a wiki where characters share their first/last names with the Japanese voice actors page and it's completely fine to leave it like that without disambiguation page. Well, that's just my opinion.
