I think there are two ways to do this.

1. Adjust the list of flowables (leaving out ListOfFiguresSection) for the front_matter document part in the template confguration:

[front_matter]
flowables = [
    TableOfContentsSection(),
    ListOfTablesSection()
]

2. Hide the ListOfFiguresSection in the stylesheet:

[list of figures section]
hide = true

Note that the 'list of figures section' selector was broken until very recently, so 2 might not work unless you're running the master branch version of rinohtype.

Again, not tested...
