Questions

Is there a KiCad symbol and footprint for the LP5569ARTW?

Yes. The symbol is Celestial_Driver_LED:TI LP5569ARTW and the footprint EasyEDA_Cloud:WQFN-24_L4.0-W4.0-P0.50-TL-EP2.5, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LP5569ARTW?

WQFN-24-EP(4x4), with 25 pins. Its footprint is drawn on this page.

Where is the LP5569ARTW datasheet?

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

Where can I order the LP5569ARTW?

JLCPCB lists it as part C701968, with 30 in stock; the sellers' links on this page open their listings.

What can replace the LP5569ARTW?

Parts like it in the library: the LP5569RTW by Texas Instruments and the LED7706 by STMicroelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
