LS_COLORS only selects colors, it doesn't enable/disable.
If unset a color set internal to ls is used.
Aliases are not used in shell scripts.
For interactive shell you can avoid with leading \ or with env:

  \ls -l
  env ls -l

cheers,
Pádraig.

p.s. since v8.23, environment variables can be used to disable ls colors,
but that's a big hammer since it's for ls to honor terminal capabilities.
To disable colors for ls (but also have other side effects):

  LS_COLORS= TERM= COLORTERM= ls -l
