Facetime calls list if phone is lost

No, Apple is not tracking nor monitoring nor logging your chats, cellular or VOIP calls, nor your emails or any other communications you do with your device.

Call logs and such live on your device, and in your itunes or icloud backups, neither of which Apple has access to.

No, since that data only lived on your device itself. So if you never backed it up, then that data is not available anywhere.

Unlike just about every other technology company, Apple does not have copies of any of your data. Your data is yours, and not accessible to Apple.
