Questions

Is there a KiCad symbol and footprint for the 2N3903?

Yes. the footprint EasyEDA_Cloud:TO-92-3_L4.8-W3.7-P1.27-L-1, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the 2N3903?

TO-92-3, with 5 pins. Its footprint is drawn on this page.

Where is the 2N3903 datasheet?

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

Where can I order the 2N3903?

JLCPCB lists it as part C3202037, with 0 in stock; the sellers' links on this page open their listings.

What can replace the 2N3903?

Parts like it in the library: the KSP94BU-FS by onsemi, the STPSA92 by STMicroelectronics, the STX83003 by STMicroelectronics and the ZTX951 by Diodes Incorporated. Check their datasheets: a part that fits the footprint may still differ in its ratings.
