How can I adjust the curvature of multiple joined lines, like adjusting a curved anchor point?

Question

I'm a beginner, and I don't know what keywords to use to search for this problem. LOL.

I need to make the highlighted parts of my object curved, which I tried to achieve by using the Blend tool to join multiple lines of width to make the shape I wanted (inspo attached), but it made the shape jagged. What can I do? TYIA!

What I need help on.Inspo.

You could draw a shape in front of the lines, select both and use a script (SplitPath.jsx) by Sergey Osokin:

As a beginner you may also explore the capabilities of clipping masks, compound clipping masks, the Shape Builder tool, Live Paint, Pathfinder, the Shaper tool and sometimes even the Eraser tool.
