I have a segment (not list) of 13K subscribers that I want to subsegment further by email “starts with”. I want to send to groups of ~500-600, so for the first batch, I started creating a segment “email starts with aa” or “email starts with ab” or “email starts with ac” all the way up to “email starts with am”. I feel like this is a very error prone way.
What’s the shortcut / best practice?

If you are looking to maintain an existing segment definition and then adjust it, you may find it helpful to start by cloning the original segment. This will generate a new segment with the original definition, which you can then edit.
You could also try taking a random sample of your larger segment (the linked doc says “lists,” but this works for segments as well!). Just note that if you pull multiple random samples, they will not always be mutually exclusive (ie, two random samples could have overlapping members).
Hope that helps get you closer to your goal!
