Is there a KiCad symbol and footprint for the ULN2003?
Yes. The symbol is Transistor_Array:ULN2003 and the footprint Package_SO:SOIC-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 ULN2003?
SOP-16, with 16 pins. Its footprint is drawn on this page.
Where is the ULN2003 datasheet?
Jiangsu Changjing Electronics Technology (CJ) publishes it: the Datasheet link on this page opens it.
Where can I order the ULN2003?
JLCPCB lists it as part C2829422, with 4,627 in stock; the sellers' links on this page open their listings.
What can replace the ULN2003?
Parts like it in the library: the ULN2003A by Mixic, the ULN2003D1013 by STMicroelectronics, the ULN2004D1013 by STMicroelectronics and the ULN2003ALM/TR by HGSEMI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
