Have you ever seen this marking scheme without "ST" in the first row? CAN it even be legitimate?

In normal times I would never thinking about buying from a no-name small Chinese seller, but I'm very desperate ATM

I never have. Also doesn't match the marking on the datasheet.

NO

I don't think this is an ST product because it should be something like the following image.

I wouldn't be surprised this to be an early 2008-vintage specimen. Their marking evolved during time, see for example pictures of the first Disco VL board.
