What would be the average cost to build a house in Los Angeles

Not including the land… You’d likely have to import builders from states where large cob (straw and earth, compacted with a ram, AKA a “rammed earth structure”) houses over 120 square feet are legal.

Like Arizona. Because if they’re larger than 120 square feet in California, they violate the building code.

So call it $1M + architects fees for adapting the structure to the steeper slope.

And then call it another $10M to get the building codes changed to specify building code for cob structures in California, so that it was actually legal to build the thing.

Alternately, you could change construction materials and methodology to something that was actually legal to use in building something that big in California.

Prestressed cast-in-place construction — which would likely not be usable for the roof slabs — you are looking at $250/square foot, on average for materials alone, so call it ~$450/square foot.

So minimally? $900,000 + architects fees, with some roof and interior second level floor pre-stressed parts built and shipped from China, with transportation to the build site — about $1M + architect fees.

And you don’t have to get the building codes changed to allow what is essentially earthen construction in a state and area prone to earthquakes — and therefore not prone to building code changes — bonus! You save $10M!
