Questions

Is there a KiCad symbol and footprint for the L4963W?

Yes. The symbol is EasyEDA_Cloud:L4963W and the footprint Package_DIP:DIP-18_W7.62mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the L4963W?

DIP-18, with 18 pins. Its footprint is drawn on this page.

Where is the L4963W datasheet?

STMicroelectronics publishes it: the Datasheet link on this page opens it.

Where can I order the L4963W?

JLCPCB lists it as part C1355476, with 0 in stock; the sellers' links on this page open their listings.

What can replace the L4963W?

Parts like it in the library: the L4973V5.1 by STMicroelectronics and the L4973V3.3 by STMicroelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
