Some blocks in published pages do not exist

All of these pages appear in the sitemap, so they are being indexed by google.

Context: found using https://github.com/alexcarol/sidekick-library-generator (it generates the library, but reports any blocks found that don't exist in the code).
The url provided is just the first url where the block is found, but there could be more than one instance of the block on the site.

Start with the listed published URLs and run the sidekick-library-generator mentioned in the issue to reproduce the missing-block report. Compare each reported block with the website code and check whether it appears on additional pages; done means the reported published blocks are accounted for in the code or the issue is narrowed to the missing implementations.
