None of these options are available to me, I’ve reverted to Siri classic until I can get confirmation that this new version is at least as good as what came before.
Sorry, it seems like the user you replied to just relied on an AI response to provide their answer and did not actually test on a device. You are correct there is no such Setting of Siri & Apple Intelligence or Siri & Search on iOS 27 and there is no option for Personal Requests in that location either.
On my device using Siri AI, I am able to add items to my Shopping List using my AirPods when the phone is locked and I have not found any Setting that would be different where it would not work for you. I also have not found anyway to prevent the ability to add items to the Shopping List through the AirPods when the phone is Locked. One other thing I can recommend is to make sure your AirPods are using the latest Firmware version as mine is showing 9A348. Check the Support Article here to see if you are on the latest version and the steps to update.

Another thing that may be worth trying is to retrain your voice by going to Requests in the Siri Settings and turn it off, then back on. I am using the iPhone 17e and see that you and another user have the iPhone 16 Pro, where I would not expect that the iPhone 17 or greater to be a requirement and it is not documented that is the case. To get an answer from Apple for what you are experiencing, I could only recommend to contact them directly or if you have an Apple Store nearby, schedule an appointment where you can show them exactly how it is working on your device.
It would be nice to get some kind of answer from Apple why it can be working for some with Siri AI on a locked phone using AirPods and not others.
