Questions

Is there a KiCad symbol and footprint for the LR2903D?

Yes. The symbol is EasyEDA_Cloud:TSB712IST and the footprint Package_SO:SOP-8_3.76x4.96mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LR2903D?

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

Where is the LR2903D datasheet?

Leshan Radio (LRC) publishes it: the Datasheet link on this page opens it.

Where can I order the LR2903D?

JLCPCB lists it as part C2846988, with 3,620 in stock; the sellers' links on this page open their listings.

What can replace the LR2903D?

Parts like it in the library: the LM2903DR by UMW, the LM393ADR by UMW, the LM393 by MSKSEMI and the LM393DRG by HANSCHIP semiconductor. Check their datasheets: a part that fits the footprint may still differ in its ratings.
