When you call use_stylesheet() in your action template, it won't
create a <link> tag instantly, but it adds the file to the response's
stylesheets. [1]
Later, when your output is decorated with the layout, and when the
processing gets to the include_stylesheets() call in hour <head> (hope
you include css like this) it will add the neccessary css too [2],
besides the others defined in your view.yml.
If you need action-specific css, use_stylesheet() is the best option you have.
