TMZ broke the story ... the L.A. County Probation Department believes LiLo violated her probation by drinking the tea, because it contains a very small amount of alcohol ... 0.5%.
But the guy who owns the company -- GT Dave -- tells us it's a "ridiculous" move because "it's like punishing Lindsay for taking a dose of cough syrup or a small amount of vanilla extract."

GT says he personally warned Lindsay about the microscopic alcoholic content of his drink last year -- and Lohan assured him she cleared it with her legal team and probation officer, even referring to the drink as a "non issue."
We'll have to see if the judge agrees.
