Lindblad converted a three-way share of the third-round lead into a nailbiting one-shot victory at the LA Championship with a closing four-under-par 68 on Sunday (Monday AEST).
The 25-year-old former world amateur No.1 prevailed after fellow tour rookie Akie Iwai bogeyed the last hole trying to match Lindblad's 21-under total to force a playoff.
Germany's 2024 Olympic silver medallist Esther Henseleit fired a bogey-free 64 to share third with Iwai's fellow Japanese first-year LPGA player Miyu Yamashita (66) and American Lauren Coughlin (70).
Lee bogeyed the last hole in a round of 69 to settle for a tie for seventh with South Korean former world No.1 Jin Young Ko (66), with Green one stroke further back in joint-ninth after a final-round 67.
Green had been bidding for a title hat-trick after winning the previous two editions of the LA Championship played at Wilshire Country Club.
But the world No.5 and 2019 PGA PGA Championship winner showcased her credentials for a second career major next week in Texas with another classy performance at the tournament's temporary new host venue, the El Cabarello Country Club.
Green posted all four rounds in the 60s, while fellow West Australian Lee will rue a disappointing third-round 70 that left the dual major winner chasing all day on Sunday.
Lee leaked four shots in a disastrous four-hole stretch on Saturday featuring four missed putts inside four feet.
The four-stroke lapse ultimately proved the difference as the former world No.2's 18-month title drought continues.
Nevertheless, Lee boasts three top-10s and a tie for 11th from six starts in 2025 and should arrive at the Chevron Championship in a confident mood for the season's first major starting on Thursday.
World No.1 Nelly Korda is the reigning champion and warmed up for her title defence with a tie for 16th in Los Angeles after closing with an even-par 72.
Australian Steph Kyriacou also shared 16th at 14 under following a final-round 68.
Lindlblad is the second Swede in as many events to win on the LPGA Tour after Madelene Sagstrom beat Coughlin in the final of the Match Play in Las Vegas a fortnight ago.
The champion paid tribute to her idol, legendary countrywoman Annika Sorenstam after her watershed win.
El Caballero was hosting an LPGA event for the first time since 2004, when Sorenstam won the Office Depot Championship.
"It means a lot. She's done a lot for us in women's golf and she's a big inspiration," Lindblad said after holding on with seven straight pars down the stretch.
"I was still in some rough, but I made a couple birdies on the front nine and then kind of just slowed down on the back.
"Obviously, I feel like I could have even had a couple more on the back nine but here we are."
