Nah, Kiro outclasses Sagisō in just about every except for sheer skill in combat, and perhaps innate viciousness.
However, you're being so cautious that your advantages in speed, versatility, sheer power, chakra potency, and just about anything else can't be used in dish out direct damage to her.
For example, you vastly outclass her base speed with LCM, yet you've never used said speed in an actual attack. What you did, was use said speed to take distance and then throw Kunai at her. Kunai aren't affected by LCM. All your attacks with the clone so far don't involve taking advantage of LCM's speed, so honestly you might as well not have been in LCM.
