The "money" the AI companies have are basically just promises from backers. If they cannot deliver their promises (which boil down to basically knowledge industries replacing around 20% of their workforce with LLMs) then that imaginary money dries up. Remember, there are real bills in the form of power and cooling and hardware that have to be paid all the time just to keep running in place.
A lawsuit that convinces the public and investors that LLMs are a dead end will kill most LLM companies.
