Questions

Is there a KiCad symbol and footprint for the LE30CD-TR?

Yes. The symbol is EasyEDA_Cloud:L4931CD33-TRY 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 LE30CD-TR?

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

Where is the LE30CD-TR datasheet?

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

Where can I order the LE30CD-TR?

JLCPCB lists it as part C2965316, with 20 in stock; the sellers' links on this page open their listings.

What can replace the LE30CD-TR?

Parts like it in the library: the LP2951ACMX-3.0 by Texas Instruments, the LP2951CMX-3.0 by Texas Instruments, the MIC5236-3.0YM by Microchip Technology and the TPS7330QD by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
