Common components all have symbols in the KiCad standard libraries.

For others, just use https://github.com/Steffen-W/Import-LIB-KiCad-Plugin or similar to import from an online source. Also grabs 3D models.

Worst case, you can draw custom footprints pretty easily.

AI is good but it tends to fall down when it comes to multiple conflicting design constraints, supply chain conditions, thermal considerations, mechanical considerations, and other concerns which are not same-domain as an electronic connectivity topology problem. Let's not get started on environmental factors, firmware hacks, board house physics, or assembly labor optimization.
