Questions

Is there a KiCad symbol and footprint for the LM393D?

Yes. The symbol is Comparator:LM393 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 LM393D?

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

Where is the LM393D datasheet?

Texas Instruments publishes it: the Datasheet link on this page opens it.

Where can I order the LM393D?

JLCPCB lists it as part C67470, with 199,939 in stock; the sellers' links on this page open their listings.

What can replace the LM393D?

Parts like it in the library: the LM2903D by Texas Instruments, the LM293DT by STMicroelectronics, the TLV1812QDRQ1 by Texas Instruments and the LMV393TPL1-SR by 3PEAK. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the LM393D?

1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
