Questions

Is there a KiCad symbol and footprint for the HT7718B?

Yes. The symbol is EasyEDA_Cloud:BL8531CB5TR50 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 HT7718B?

SOT-23-5, with 5 pins. Its footprint is drawn on this page.

Where is the HT7718B datasheet?

Holtek Semicon publishes it: the Datasheet link on this page opens it.

Where can I order the HT7718B?

JLCPCB lists it as part C259885, with 0 in stock; the sellers' links on this page open their listings.

What can replace the HT7718B?

Parts like it in the library: the LM3671MFX-1.8 by Texas Instruments, the TPS62202DBV by Texas Instruments, the XC9236A18CMR by Torex Semiconductor and the LM3671MF-1.8 by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
