Maybe all we need is to add a hook that will be called by
kmacro-call-macro before running the macro.  Then users can do
whatever they like in that hook, including turning off
line-move-visual (which I'm guessing is what you meant, not
visual-line-mode).

We could also have a new user option to turn that off automatically
while running a macro, but that sounds too specific to some uses of
macros in some use cases, not something many users will want in many
cases.
