Yes those are optional systems that exist, but they are unrelated to the autopilot (in at least the vast majority of avionics).
They are warning systems that humans respond to. For a TCAS RA the first thing you're doing is disengaging the autopilot.
If you tell the autopilot to fly straight into the path of a mountain, it will happily comply and kill you while the ground proximity warnings blare.
Humans make the decisions in planes. Autopilots are a useful but very basic tool, much more akin to cruise control in a 1998 Civic than a self-driving Tesla/Waymo/erc.
