I don't know what will kill "everything" but they stuff they use on
corn fields sure kills everything except corn. So you might use
something like that, unless you're being overrun by corn.

Except for 2,4-D (broadleaf only) and Roundup (generically, glyphosate)
it's virtually all others are restricted-use herbicides and what is used
is almost always a combination of several.

For OP, Roundup is the choice...possibly add a little 2,4-D but the
other broadleaf he mentions such as the dandy-lions are pretty easy. Of
course, dandelions _in_ the yard where he wants to keep the grass is
2,4-D, _not_ Roundup. (And, he'll probably get some browning of the
Bermuda, but it won't kill it).
