Hm, why do you have to say that? A CV is expected to be super polished and not necessarily consistent with the rest of your writing, right?

If I were asked a direct question, especially in a job interview, I would be truthful. That answer stops any sniping about using AI and lets me focus on my skills.

Ah, I misunderstood the parent comment as having that disclaimer on the CV itself.

I agree that if asked directly, it makes sense to talk about candidly. Hopefully an employer would be happy about someone who understands their weak spots and knows how to correctly use the tools as an aid.

Asking about AI usage in CV is pointless in my opinion. You are always responsible what reads in there. If they don’t like the writing style, then they don’t.

Interviewers directly asking whatever bothers them is fine IMHO. The alternative is keeping a negative impression when there could have been an insightful exchange, and the candidate also gets to know what to expect from the company.

If you have access to Microsoft Word, I'd customize the grammar checker settings to flag more than what is enabled by default. They have a lot of helpful rules that many are oblivious to because it's all buried deep in the preferences. Then adopt the stance of taking the green lines under advisement but ignore them if your original words suit your preference. That will get you polished up without submitting to AI editorial mundanity.
