Questions

Is there a KiCad symbol and footprint for the AP2191WG?

Yes. The symbol is EasyEDA_Cloud:AP22817AKEWT-7 and the footprint Package_TO_SOT_SMD:SOT-23-5, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the AP2191WG?

SOT-25-5, with 5 pins. Its footprint is drawn on this page.

Where is the AP2191WG datasheet?

Diodes Incorporated publishes it: the Datasheet link on this page opens it.

Where can I order the AP2191WG?

JLCPCB lists it as part C141321, with 21 in stock; the sellers' links on this page open their listings.

What can replace the AP2191WG?

Parts like it in the library: the SY6280AAC by 矽力杰silergy, the AP2171WG by Diodes Incorporated, the TPS2051BDBV by Texas Instruments and the RT9742CGJ5 by RICHTEK. Check their datasheets: a part that fits the footprint may still differ in its ratings.
