I think BriGuy and I both put in enough time to figure out exactly what the Qix will do.
(I suspect the majority of our deaths came from playing too aggressively and "missing" a segment that should have reconnected in time, or accidently letting a sprite/spark hit us while we were focused on Qix behavior)
I won't say they're fully controllable, but they can definitely be manipulated.
And while their motion SEEMED erratic, the main thing is that you just have to pay attention to their apparent max speed and their total distance from your cursor.
Once you start drawing they are magnetized to your cursor, at varying levels of intensity, based on your in-game level.
Exploiting that is one of the methods for trapping them in tiny spaces.
Basically, you draw a tiny space with a "ledge".
Then you draw a partial line, hidden behind the ledge, and just sit there, with an uncompleted line, as long as possible (without the fuse hitting you, of course).
The longer the partially drawn line sits there, the stronger the attraction from the Qix becomes, until it gets sucked into the small space.
You finish your line while they're on the way into the trap, and then close out the trap quickly to finish the level.
That mechanic is why the larger the line you try to draw at once, the more quickly the Qix seem to come thwart your plans.
