How does one expose a property that's a dict on the LP API? Are there
any examples of this?

Because it's a boring implementation detail of no actual use. It's
sole purpose is to allow us to associate a mapping from pocket ->
branch with each source package.

If we weren't using an ORM, it wouldn't be a class at all.

TBH, I'm not sure why it's a list of tuples rather than a dict. I don't
know how to expose a dict over the API. Surely someone has done it
before though.
