LND and Core Lightning are very different implementations of Lightning. Other apps with them as a dependency will typically be built to work with one or the other.
The reason Alby Hub has LND only as an optional dependency is because Alby Hub can run on its own without an existing LND node. Alby Hub has LND built in and can therefore be its own Lightning node.
That said, I recommend using LND + Alby Hub for the most versatility, and so you can manage your node using other apps like Ride the Lightning or Thunderhub, too.
