LiteTween is the greatest addon for tweening, you won't find a better one.
Just set Tweened Property=Value, and set sprite angle to Sprite.LiteTween.Value on every tick while the tween is running.
However, I just tested and it looks like you can do this by tweening the angle directly. Say, if you want to rotate your sprite 30 degrees clockwise, tween to (sprite.angle+30). If you need to rotate counter-clockwise, tween to (sprite.angle-30)
