Where did 'IntelDataApi' come from and why is my deploy failing because of it?

any reference to Intel* in the openapi.yaml file?

Nowhere in my project at all. The issue recurred yesterday with an entirely new resource name and I have seen this multiple times in the past as well. I can try the same deploy multiple times in a row, get the air once, then the next deploy attempt will work perfectly. More recently I decided to seek out help because I was completely locked out and ended up having to delete the stack and redeploy it rather than being able to update it.

Can you create an issue in the SAM repo? I think this is best tracked there since CloudFormation calls SAM to do the transformation
