Is there a KiCad symbol and footprint for the LM4548AVH?

Yes. The symbol is EasyEDA_Cloud:LM4548AVH and the footprint Package_QFP:LQFP-48_7x7mm_P0.5mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LM4548AVH?

LQFP-48(7x7), with 48 pins. Its footprint is drawn on this page.

Where is the LM4548AVH datasheet?

Texas Instruments publishes it: the Datasheet link on this page opens it.

Where can I order the LM4548AVH?

JLCPCB lists it as part C3213317, with 0 in stock; the sellers' links on this page open their listings.

What can replace the LM4548AVH?

Parts like it in the library: the CM108B by Cmedia, the ADAU1701JSTZ-RL by Analog Devices, the PCM9211PTR by Texas Instruments and the HS-100B by Cmedia. Check their datasheets: a part that fits the footprint may still differ in its ratings.
