Essentially the amount of water/chemicals they can move is trivial compared to land approaches
I'm sure that's correct for many geographies, but most of this fire is burning on steep mountainsides and in canyons without road access, or an occasional dirt road and no water connection. With the amount of wind, probably nothing could be done, land or air, once this started.
Even the populated areas in the Palisades fire have roads that are remarkably poor. A lot of them are windy, with negligible visibility around corners, and are barely a single lane. I doubt that a fire truck can get through many of them easily even under ideal conditions.
