Questions

Is there a KiCad symbol and footprint for the NE555D?

Yes. The symbol is Timer:NE555D and the footprint Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

Where is the NE555D datasheet?

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

What can replace the NE555D?

Parts like it in the library: the LTA8062XS8/R8 by Linearin, the SD8568 by WAVE, the FH9926 by XIN FEI HONG and the LTC8836XS8/R8 by Linearin. Check their datasheets: a part that fits the footprint may still differ in its ratings.
