… but I’m getting the lines by “extracting” mesh edges by index. Would it still be beneficial to do this?

That shouldn’t matter. A Rhino.Geometry.Line is a Rhino.Geometry.Line right. And indeed, wrapping these in a Grasshopper line type does appear to speed things up, but not as substantial as with more complex geometry types:

The crash must be caused by data accumulation somehow

This does sound more like a memory leak-type issue to me as well.

How do I declare one in order to store my class object?

Have a look here:

Note that using a non-unique sticky key (i.e. "x") means that another instance of this GHPython component (or anything else that can access the sticky) can mess with this sticky value (leading to all sorts of potential trouble). A couple of ways around this: Get the guid of the GHPython component and append this to the key (example here), making the key value unique to the specific GHPython component instance (meaning you can copy/paste it). Or better yet: Use the if “foo” not in globals() …
