Questions

Is there a KiCad symbol and footprint for the L6902D?

Yes. The symbol is EasyEDA_Cloud:L6902D013TR and the footprint Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the L6902D?

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

Where is the L6902D datasheet?

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

Where can I order the L6902D?

JLCPCB lists it as part C2070941, with 0 in stock; the sellers' links on this page open their listings.

What can replace the L6902D?

Parts like it in the library: the XL1509-5.0E1 by XLSEMI, the XL1509-ADJE1 by XLSEMI, the XL1410E1 by XLSEMI and the MC34063AD by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
