0 for operator is also configured as the client specifies. If they don’t want it, it’s not there.
FYI, those systems aren’t AI at all other than optional speech recognition. On the other hand I generally don’t have a problem using a phone voice recognition system, and neither do the majority of Americans. Speak clearly, at a measured pace, in a quiet area and they do fine. Do NOT get loud or shout at it - at least some of them can be configured that an apparently irate caller shouting at it will deliberately be disconnected. Which, when I worked at a call center, was something I dearly wanted to be able to do on calls with idiots.
Also, a good voice menuing system is actually cheaper than one receptionist - and able to handle much higher call volumes with greater accuracy.

LOL!
Next you’ll be telling me most people like telemarketers and robocalls!
