In LFSv2, all of the addressing should be in fragments (though
i_ffs_blocks is in sectors, like FFS); but you're right that in version 1
filesystems everything is defined in terms of sectors.

Believe me when I say I know how frustrating that can be :^)

Yes, I think it is a bug.  I'll look at it tonight, though I think that
just putting the first btofsb inside the fsbtodb might take care of it.
