Questions

Is there a KiCad symbol and footprint for the TDA7705?

Yes. The symbol is EasyEDA_Cloud:TDA7705 and the footprint Package_QFP:TQFP-64_10x10mm_P0.5mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the TDA7705?

TQFP-64(10x10), with 64 pins. Its footprint is drawn on this page.

Where is the TDA7705 datasheet?

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

Where can I order the TDA7705?

JLCPCB lists it as part C1526100, with 0 in stock; the sellers' links on this page open their listings.

What can replace the TDA7705?

Parts like it in the library: the TDA7706M by STMicroelectronics, the CC1010-RTY1 by Texas Instruments, the CC1010PAG by Texas Instruments and the CC1010PAGR by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
