Questions

Is there a KiCad symbol and footprint for the L6591?

Yes. The symbol is EasyEDA_Cloud:L6591TR and the footprint Package_SO:SO-16_3.9x9.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the L6591?

SO-16, with 16 pins. Its footprint is drawn on this page.

Where is the L6591 datasheet?

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

Where can I order the L6591?

JLCPCB lists it as part C2970893, with 57 in stock; the sellers' links on this page open their listings.

What can replace the L6591?

Parts like it in the library: the L6599D by STMicroelectronics, the L6599AD by STMicroelectronics, the L6566B by STMicroelectronics and the L5991D by STMicroelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
