Ravenous Bugblatter Beast of Traal
Here's the first paragraph of the overview for Storm King's Thunder:Where? I've certainly never read one with that text written anywhere.
This 256-page adventure for characters of 1st level to 11th level or higher provides everything a Dungeon Master needs to create an exciting and memorable play experience for the Storm King’s Thunder story, including rune magic items, a new treasure option for characters.

The first bullet point for Curse of Strahd:
A fantasy-horror adventure for characters levels 1-10, Curse of Strahd provides everything a Dungeon Master needs to create an exciting and memorable play experience
Of those I checked many of the others imply it, but these have the "provides everything" verbiage that isn't debatable.
This is absolutely how they are marketed - as ready-to-play adventures.
I put the same burden of proof back on you - I've never read anything along the lines of "this adventure is not ready to run and must be adapted by the DM first".
The only place I can find anything like that is Tales of the Yawning Portal, which talks about "seven of the most compelling dungeons" and then says "The seeds of these stories now rest in your hands", which does imply that you need to take hem from seeds to full blown adventures. This isn't any stronger then the implication from most of them that they are ready to run.
Because if I can show proof that adventures are sold as ready to run to your criteria and you can not show proof that the are sold as explicitly not ready to run to your own criteria, I would expect that we have a clear and factual call in this case.
