Hi, @viktor89, what @jcespinoza says is correct. You can also append something like ls -R publish_directory_here or tree publish_directory_here to your command to log to the build logs the files in the deploy to the build logs.
Using @jcespinoza solution will likely be much less effort in most cases though.
Would you please check one way or other and let us know if the Git LFS tracked files are in the publish directory? Also, would you please confirm the content of the files themselves to see what they contain?
I ask because files in Large Media should only have their Git LFS text pointer in the deploy and not the actual file. Here is an example of the text pointer content Git LFS tracked file:
version https://git-lfs.github.com/spec/v1
oid sha256:36fbd35d988b57f856450f764cbc47aee4ba7c441de89822d6ee2d8c6c24aee7
