Just import your style templates in your templates or hardlink them

<xf:include template="your.less" />
<xf:css src="your.less" /> <!--unversioned-->
<link rel="stylesheet" href="{{css_url('path/to/your.css')}}" /> <!--versioned-->

If you want the css on every page or a specific stock template, create a template modification on helper_js_global (or the given stock template) and inject your css with one of the methods above this way. You can bind template modifications to your addon.
Otherwise, if you need your css on specific templates you created yourself, then just insert one of the methods above in your template.
