Smith declined to specifically address his felony gun charges and DUI charge in Santa Clara County Superior Court nor his April 13 arrest at LAX for a fake bomb threat during the interview.
The Los Angeles Court Attorney's office has been mulling potential misdemeanor charges for several weeks.
Smith told the station he is waiting for the truth to come out in the case.
"Maybe after this is over, you can tell your friends I'm a good person," Smith told CSNBayArea.com. "Anybody who hangs around me can tell that. A lot of these things are being painted in a picture that's not true."
Smith pointed to the 49ers' backing of him as proof he is not a "thug." The 49ers picked up Smith's 2015 option for $9.754 million on May 2, just hours before the deadline.
The 49ers can still pull the option before the start of the 2015 league year next March.
"The 49ers have supported me," Smith said. "As you can see, the option got picked up. And if I was a thug or something, I don't think they'd take those chances."
Smith, 24, has 42 sacks in 43 regular-season games.
