Questions

Is there a KiCad symbol and footprint for the AH542SS?

Yes. The symbol is EasyEDA_Cloud:AH545SU and the footprint Package_TO_SOT_SMD:SOT-23, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the AH542SS?

SOT-23, with 3 pins. Its footprint is drawn on this page.

Where can I order the AH542SS?

JLCPCB lists it as part C5378273, with 0 in stock; the sellers' links on this page open their listings.

What can replace the AH542SS?

Parts like it in the library: the UHE4913G-AE3-R by UTC, the HAL2041SO by Hallwee, the DRV5032FADBZ by Texas Instruments and the CC6207MST by Cross chip. Check their datasheets: a part that fits the footprint may still differ in its ratings.
