Interference? Or, no call?

[NCASAUmp]

For me, I had better see *some* kind of attempt by the fielder to make a play other than simply "turning left." How did she react after she turned left? Did she take a surprised step back? Did she flinch and start to dodge? I'll admit I don't remember USSSA's wording for interference (it's been 12 years, and it's probably changed since then), but I doubt it's all that different from ASA.

If I'm going to call a runner out for INT, I had better be positive that it was INT. It doesn't sound like you were at that point with these calls, so I think you were right in not calling INT. Strange things do happen, man.
