Overview
The 1N4448 is a switching Diode made by STMicroelectronics in a DO-35 package with 2 pins. 1 Independent 150mA 4ns 500mA 500mW 5uA@75V 720mV@5mA 75V DO-35 Switching Diodes ROHS.
PCBKit's library has its KiCad symbol (Diode:1N4448, from KiCad's library) and its footprint (Diode_THT:D_DO-35_SOD27_P7.62mm_Horizontal, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C54037).

Questions
Is there a KiCad symbol and footprint for the 1N4448?
Yes. The symbol is Diode:1N4448 and the footprint Diode_THT:D_DO-35_SOD27_P7.62mm_Horizontal, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the 1N4448?
DO-35, with 2 pins. Its footprint is drawn on this page.
Where is the 1N4448 datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the 1N4448?
JLCPCB lists it as part C54037, with 0 in stock; the sellers' links on this page open their listings.
What can replace the 1N4448?
Parts like it in the library: the BAV21W by MDD, the 1N4148 by LGE, the 1N4148 by onsemi and the 1N4148TR by FUXINSEMI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
