Questions
Is there a KiCad symbol and footprint for the HT7818?
Yes. The symbol is Pinmap_Generic:Regulator_Linear_1IN_2GND_3EN_4NC_5OUT and the footprint EasyEDA_Cloud:SOT-23-5_L2.9-W1.6-P0.95-LS2.8-BL, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the HT7818?
SOT-89-3, with 5 pins. Its footprint is drawn on this page.
Where is the HT7818 datasheet?
Holtek Semicon publishes it: the Datasheet link on this page opens it.
Where can I order the HT7818?
JLCPCB lists it as part C259572, with 553 in stock; the sellers' links on this page open their listings.
What can replace the HT7818?
Parts like it in the library: the AP2112K-1.8TRG1 by Diodes Incorporated, the ETA5055V180DD1E by etasolution, the AMS1117-1.8 by UMW and the AMS1117-1.8 by Advanced Monolithic Systems. Check their datasheets: a part that fits the footprint may still differ in its ratings.
