Is there a KiCad symbol and footprint for the KA7809B?
Yes. The symbol is Pinmap_Generic:Regulator_Linear_1IN_2GND_3OUT and the footprint EasyEDA_Cloud:TO-220-3_L10.0-W4.5-P2.54-L-1, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the KA7809B?
TO-220, with 3 pins. Its footprint is drawn on this page.
Where is the KA7809B datasheet?
FeiHong publishes it: the Datasheet link on this page opens it.
Where can I order the KA7809B?
JLCPCB lists it as part C438775, with 0 in stock; the sellers' links on this page open their listings.
What can replace the KA7809B?
Parts like it in the library: the 7809 by Foshan Blue Rocket Elec. Check their datasheets: a part that fits the footprint may still differ in its ratings.
