Are there any know design for self flying kite the could pull up the wind at specified angle?
This not specifically for kite surfing but to propelling devices from windmills to boats.
I imagine that this kite once lunched should stay or travel within specific angle to the wind without intervention from the bottom.
The only thing I know of that would come close to what you describe would be the Peter Lynn "Arc" . You could tie that thing to a pole while you went home for lunch and it would still be up there when you got back to it

Another option ive seen that has "legs" is a single line parafoil, with an adjustable drogue off the trailing edge. The drogue provides extra drag and stability, but you can adjust its position on the trailing edge so the drag can pull the kite to one side of the window - right on the very edge and parafoil sits low and pulls more across the wind. Set the drogue more in the middle and the foil sits higher and pulls more downwind.
They're very cheap, compact and super easy to launch. Super stable so its pretty close to set and forget.
Going upwind is a still a challenge - the more you get the foil near the edge , the less stable it gets. Still a long hull boat will certainly beam reach with this set up.
