Is there a KiCad symbol and footprint for the KY3232LEEN?
Yes. The symbol is EasyEDA_Cloud:MAX232EIN_C47088910 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 KY3232LEEN?
SOIC-16, with 16 pins. Its footprint is drawn on this page.
Where is the KY3232LEEN datasheet?
Keysemi publishes it: the Datasheet link on this page opens it.
Where can I order the KY3232LEEN?
JLCPCB lists it as part C428899, with 0 in stock; the sellers' links on this page open their listings.
What can replace the KY3232LEEN?
Parts like it in the library: the SP3232EEN-L/TR by MaxLinear, the SP3232EEN(UMW) by UMW, the MAX3232EID by Texas Instruments and the MAX3232ESE(UMW) by UMW. Check their datasheets: a part that fits the footprint may still differ in its ratings.
