So they US just needs to open 187 more desalination plants... and find a place to put all that deadly brine.
An instant ramen factory would at least take care of the sodium!
That said, looks like the current sea water desalination worldwide is pretty huge:

236.5 million cubic meters of sea water processed a day, 264 gallons in a cubic meter = 62.44 Billion gallons of water per day.
If the Lithium content is the same as it is in the US example, then that is a potential 20,000 tons of Lithium a year (again assuming the same Li concentration and 100% extraction.
Sadly still short of the current global demand for lithium:
