the only one that comes to mind is this:
https://www.mangago.zone/read-manga/i_became_the_daughter_in_law_of_the_villain_because_i_m_terminally_ill/
it's a long con and still ongoing, so who knows how it'll end
here the MC is a child, so she runs to the duke, but not to marry, so I guess it counts? :P

here the MC is tired of life and decides to die

A bit similar trope, but not exactly: instead of running away she takes over and sends her trashy family away:

In regression and transmigration stories the MC always talks about running away but they never actually do it.
Are there any where they just say "screw this im out" and ACTUALLY leave their scummy family? not run away to marry a duke or whatever, but actually just steal a bunch of jewelry and dip.
