I dont think "file layout" has to mean the exact location of every byte. An abstract file layout is still a file layout.

How can you literally interpret the two words "file layout" without it pertaining to the layout of a file?
We can successfully interpret the two words “guinea pig” without it pertaining to either pigs or things coming from Guinea, so I’m sure this is also possible.
I'm not sure whether 'file' necessarily has to refer to the 'Unix' view of a 'sequence of bytes'? Or just 'some organisational unit of information'? Ie like the stuff you would put into a filing cabinet?
The 'sequence of bytes' view is just one specific level of abstraction. It's not what's actually on disk because of things like compression, encryption and fragmentation.
Database schemas are a different level of abstraction.
DBs can be files on disk though? Besides they're a bit like easy hand rolling powder mix for filesystems. Filesystem entries has properties like filenames and inode numbers and file contents. Databases has columns like emails and membership IDs and their favorite cookies. I don't think "file layout" is an absurd framing.
It is in literally no sense a layout; the whole point of a schema is that it doesn't tie you down to a layout. SQL schemas make sense even in the absence of files!
You suggest that we interpret "file formats" as exactly this -- no more, no less. This approach is also called "textualism". The other option is to interpret "file formats" in the context of the law that includes these words. Or: what exactly did the lawmakers have in mind when they said that (a) government needs to provide information; (b) except for several cases, of which one is (c) "file formats". What kind of information did they think it was ok for the government not to provide?
I agree with the Court's argument that "the information about how the actual information is stored and connected one piece to another" is what the lawmakers meant in this case.
- If the actual information is stored in the files, the government does not need to disclose how these files are organized ("file formats").
- If the actual information is stored in the database, the government does not need to disclose how the database is organized (database schema).
- If the actual information is stored in the block memory -- with structs and pointers -- the government does not need to disclose the structs and the pointers.
The "textualist" opponent would of course argue, as OP did, that the second and the third example aren't excepted by clause (c) because "when there is no file, there could be no file format". This however is missing the point (in my opinion), as it doesn't see the forest for the trees.
