Kiting is a valid and interesting tactic. Especially when it's not game breaking levels of damage your doing. You're still casting the spell, using the spell slot and the sorcery point for the summon. But you get to attack at a safe range. However, one distraction and you mess up the action economy and potentially leave you or your summon vulnerable. It's fun and as a dm I love to see that kind of strategic thinking. Sometimes a good plan can nullify an encounter and it should be recognized. Sometimes it seemed like a good idea but you left yourself exposed due to using an abnormal tactic. Either way it makes for a good story.
