Questions

Is there a KiCad symbol and footprint for the ST7540?

Yes. The symbol is EasyEDA_Cloud:ST7540 and the footprint Package_SO:TSSOP-28_4.4x9.7mm_P0.65mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the ST7540?

TSSOP-28, with 28 pins. Its footprint is drawn on this page.

Where is the ST7540 datasheet?

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

Where can I order the ST7540?

JLCPCB lists it as part C472599, with 0 in stock; the sellers' links on this page open their listings.

What can replace the ST7540?

Parts like it in the library: the AD8016AREZ-REEL7 by Analog Devices and the AD8325ARUZ-REEL by Analog Devices. Check their datasheets: a part that fits the footprint may still differ in its ratings.
