When inserting LO content through a component into CMS, it will look like the below:

<div id="convio-content-834481595" class="templateComponent" style="display: inline;"></div>

You can change it to the following in order to get rid of the div tags but still have the LO content component:

<t:include id="convio-content-834481595"/>

This is making use of the CMS template language. The documentation for this can be found here.
