Yes.  But the the amount is very, very small.  Somewhat more than 50%
of the world's oxygen comes from the top meter or so of the oceans.
At least 30%, by the last estimate I remember, comes from forests,
rain forests, and similar large-scale O2 producers.

Your lawn does indeed contribute to the total O2, but I wouldn't
worry about it.  On the other hand, if I owned a house & thought could
get away with letting the grass grow long, I would.  The reasons
not to do this include ticks, fleas, and assorted insects.
