Questions

Is there a KiCad symbol and footprint for the LM2903ST?

Yes. The symbol is Comparator:LM2903 and the footprint EasyEDA_Cloud:MINISO-8_L3.0-W3.0-P0.65-LS4.9-BL, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LM2903ST?

MiniSO-8, with 8 pins. Its footprint is drawn on this page.

Where is the LM2903ST datasheet?

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

Where can I order the LM2903ST?

JLCPCB lists it as part C2970318, with 1,895 in stock; the sellers' links on this page open their listings.

What can replace the LM2903ST?

Parts like it in the library: the LM2903YST by STMicroelectronics, the TS883IST by STMicroelectronics, the LM2903WHYST by STMicroelectronics and the TSX393IST by STMicroelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
