Is there a KiCad symbol and footprint for the LP5569RTW?

Yes. The symbol is EasyEDA_Cloud:LP5569RTWR 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 LP5569RTW?

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

Where is the LP5569RTW datasheet?

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

Where can I order the LP5569RTW?

JLCPCB lists it as part C701969, with 448 in stock; the sellers' links on this page open their listings.

What can replace the LP5569RTW?

Parts like it in the library: the LED7706 by STMicroelectronics and the LP5569ARTW by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the LP5569RTW?
