Questions

Is there a KiCad symbol and footprint for the LS4148?

Yes. The symbol is Device:D and the footprint Diode_SMD:D_MiniMELF, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LS4148?

LL-34, with 2 pins. Its footprint is drawn on this page.

Where is the LS4148 datasheet?

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

Where can I order the LS4148?

JLCPCB lists it as part C111976, with 0 in stock; the sellers' links on this page open their listings.

What can replace the LS4148?

Parts like it in the library: the LL4148 by MDD, the LL4148PF by STMicroelectronics, the LL4148-GS08 by Vishay Intertechnology and the LL4148 by LGE. Check their datasheets: a part that fits the footprint may still differ in its ratings.
