Overview
The BC557C is a bipolar made by DIOTEC with 3 pins.
PCBKit's library has its KiCad symbol (LibrePCB_Base:BC557, from Librepcb) and its footprint (LibrePCB_Base:TO-92-WIDE_default, from Librepcb), ready for a KiCad board. JLCPCB lists it (part C6751353).

Is there a KiCad symbol and footprint for the BC557C?
Yes. The symbol is LibrePCB_Base:BC557 and the footprint LibrePCB_Base:TO-92-WIDE_default, both drawn on this page. PCBKit places them on a board for you when you design with it.
Where is the BC557C datasheet?
DIOTEC publishes it: the Datasheet link on this page opens it.
Where can I order the BC557C?
JLCPCB lists it as part C6751353, with 0 in stock; the sellers' links on this page open their listings.
What can replace the BC557C?
Parts like it in the library: the BC546B by onsemi, the BC547A by onsemi, the BC549B by onsemi and the BC556A by DIOTEC. Check their datasheets: a part that fits the footprint may still differ in its ratings.
