is OpenAI willing to have hire engineers & solutions architects work hand in hand with F500 companies for this to be possible ?

or again it's simply OpenAI looking for PMF to justify their valuations ?

I think it's the latter and will fail again just like Sora.

They have big FDE team plus acquired a consulting company

forward deployed engineers are already there for a while. i wouldnt say many years but maybe in less formal ways they did it before. often enough theres a few folks doing stuff before roles/department emerges.
