First things first:
We have a file with LF in the repo, and check it out.

Read it like this:
"eol__crlf_false_attr_auto_.actual"
                 ^ *.txt auto in .gitconfig   
      ^
      core.autocrlf is false 
  ^
  core.eol is unset

The file is expected to have LF in the working tree, but has CRLF

Which version of t0027 do you have:
The latest version in git.git is this one,
and "should pass" (but I may have missed something)

commit f6975a6b119128de1c5a89e6cd64f75ed1de2177
Author: Torsten Bögershausen <tboegi@web.de>

    t0027: Tests for core.eol=native, eol=lf, eol=crlf
    
    Add test cases for core.eol "native" and "" (unset).
    (MINGW uses CRLF, all other systems LF as native line endings)
    
    Add test cases for the attributes "eol=lf" and "eol=crlf"
    
    Other minor changes:
    - Use the more portable 'tr' instead of 'od -c' to convert '\n' into 'Q'
      and '\0' into 'N'
    - Style fixes for shell functions according to the coding guide lines
    - Replace "txtbin" with "attr"
