The <<list-links>> macro is just a short cut for using the <$list> widget. However, as you've noticed, it only outputs links to tiddlers, not content. To produce more complex output, you need to use the <$list> widget instead.
Something like this:
<$list filter="[prefix[ExcelLogo]!tag[summary]]">
<$link />:
<blockquote> <$transclude mode="block" /> </blockquote>
</$list>
1) $list matches the specified filter, and automatically sets <<currentTiddler>> for use in the widget contents
2) $link creates a link using the <<currentTiddler>> title as the default.
3) The <blockquote>...</blockquote> is standard HTML, to show the tiddler content indented with a vertical line along the left.
4) $transclude shows the content of the <<currentTiddler>>.
5) Note use of mode="block" to ensure that tables, headings and lists are formatted properly (as compared to mode="inline")
