Is there a KiCad symbol and footprint for the M74HC251T?

Yes. The symbol is 74xx:74LS251 and the footprint Package_SO:TSSOP-16_4.4x5mm_P0.65mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the M74HC251T?

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

Where is the M74HC251T datasheet?

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

Where can I order the M74HC251T?

JLCPCB lists it as part C19322939, with 0 in stock; the sellers' links on this page open their listings.

What can replace the M74HC251T?

Parts like it in the library: the SN74HC138PW by Texas Instruments, the TCA9546APW by Texas Instruments, the 74HC4851PW-Q100,11 by Nexperia and the SGM330A-YTS/TR by SG Micro. Check their datasheets: a part that fits the footprint may still differ in its ratings.
