Problems with AI Image Editors

One bit of criticism I've had about using AI (with a few editors so far) has been my inability to create drawings which are just black and white lines (no fills, gray areas, or colors).

And I've encountered the same feedback regarding various coloring books. Somehow, I plan to solve it - but I don't know how - yet.

I'm hoping I can do it by AI. That would be great if possible. If not, I will have to find a way of doing manually with Photoshop or some other image editor.

There must be a way, and I will find it. When I'm able to do so, I will be able to give users what they really want. To those of you reading this post, do you agree? Or disagree? It would be great to know your thoughts.
