Just what autistic children need for their education — Lindsay Lohan. The troubled starlet’s lawyer, Mark Heller, held a press conference outside an LA courthouse yesterday and claimed Lohan was going yesterday to an unnamed New York City school to help autistic kids. “She’s certainly not going to alert the media,” he told The Post. Heller also said Lohan was turning her life around and having intensive “one-on-one psychotherapy” in a bid to avoid more rehab: “Lindsay does not have a problem with alcohol or drugs . . . She is totally sober.” Lohan, on probation for a necklace theft, is in trouble over a crash last summer on the Pacific Coast Highway. She claimed to be a passenger, but cops say she was the driver.
