The knocking you are describing is probably rod knock -- meaning that due to improper oiling, the bearings were toasted, and bam -- dead motor.

This leads me to believe either:

(1) Faulty motor -- possible, but the lack of oil begs the question of where it went...

(2) oil pump or oil pickup failed -- again, possible, but then we'd see evidence of a destroyed oil pump gear or something major blocking the pick up in the pan -- again where is the oil?

(3) Seriously fvcked engine from improper ring sealing due to incorrect break in/poor build -- possible, but it's hard to imagine all the oil went into blowby and you would have been way down on compression and therefore power

(4) Oil leak or oil was never put back in -- the pistons and rods are coated with a dry lubricant film (I believe), so yes, it is actually possible that you had hardly any oil in there and it held together for a while before breaking -- highly unlikely, but not impossible.

(5) A combination -- not enough oil was put in, you were burning what little there was from improper ring sealing, etc. finally insufficient lubrication led to toasted bearings.

Get a lawyer.

And a leakdown test/teardown.
