You haven’t internalized the library system and the idea of “parts” or “components” in KiCad yet.
There are quite many wire connector footprints in the footprint libraries (Connector_Wire) – 326 in v9.0.3 to be exact!
There are generic symbols in the symbol libraries. You can use whatever you want, for example a generic connector symbol. Add the symbol to the schematic, attach the footprint to it.
Not all “components” or “parts” have a dedicated symbol in KiCad libraries (those words aren’t even usually used in KiCad). Rather, you will select a proper symbol and a proper footprint and combine them by assigning the footprint in the symbol Properties. Because KiCad uses this kind of system which is both powerful and flexible, it wouldn’t make much sense to have hundreds of symbols for a PCB wire connector.
Then there’s a FAQ article…
