Responsibility is an engineering choice.

Oversight is easier to implement when it is part of the original design. The same is true of privacy, security and the ability to explain how a result was produced.

Make the boundaries visible.

A useful intelligent system communicates uncertainty and its operating limits. It should be clear when a result needs expert review and when the system should decline to proceed.

Design for review.

Versioned inputs, recorded assumptions and reproducible evaluation help people challenge a result. Human oversight needs a real decision point and enough context to exercise judgement.

Responsible engineering is an ongoing practice. It requires revisiting assumptions as systems, users and the world around them change.
