I am not aware of a quote in which Jefferson advises specifically not to
build cities.  Most of what he said regarding cities was, as you say, a
critique of their effects.  The closest that come to counseling against the
building of cities are the following:

"I think our governments will remain virtuous for many centuries
as long as they are chiefly agricultural; and this will be as long as
there shall be vacant lands in any part of America.  When they
get piled upon one another in large cities as in Europe, they will
become corrupt as in Europe." --Thomas Jefferson to James
Madison, 1787.  Papers 12:442

"I view great cities as pestilential to the morals, the health and
the liberties of man.  True, they nourish some of the elegant arts;
but the useful ones can thrive elsewhere; and less perfection in
the others, with more health, virtue and freedom, would be my
choice." --Thomas Jefferson to Benjamin Rush, 1800.  ME
