Law school is 3 years. If he has a real law degree, it's not in Adrian Chase's name.

This same sentiment is shared in a piece by Albert Ching for CBR:

Ra's al Ghul died in the Season 3 finale. Talia agreed to train Adrian Chase because by that point Oliver had killed both their fathers.

His cameo in Cosmic Calendar Girls was quite unexpected.

That might explain why the didn't adapt the Seven…

No, but they do have a library to fill. A 13-episode series keeps subscribers occupied for longer.

Are we certain Agent Carter isn't the black sheep of the MCU?

Oded Fehr is an Israeli actor whose family is from Germany and the Netherlands. He is just as white as Cumberbatch.

because they had to accommodate a lot more actors' schedules

Noah Hawley calls Legion a superhero show, so I'll go with what he says.

Possibly, but let's not forget that the casting of Chiwetel Ejiofor in The Martian was criticized as whitewashing.
