Teams played foursomes on day one of the 72-hole event at Midland Country Club and Lee and Choi's teams are just two shots off the pace being set by Canadians Brooke Henderson and Alena Sharp at 5 under.
Lee and her partner Jin Young Ko as well as Choi and her Canadian teammate Jaclyn Lee opened with 3 under rounds of 67 to share 3rd place with two other teams while Americans Paula Creamer and Morgan Pressel are in outright 2nd at 4 under.
It shapes as a crucial week for Choi who has made only one of nine cuts so far in her rookie LPGA Tour season to sit 167th on the Race to CME Globe standings.
The 21-year-old needs to be inside the top 100 on the points standings at the end of October's Volunteers of America Classic to keep her LPGA Tour card.
The duo of Victorian Su Oh and England's Mel Reid are part of an 8-team tie for 12th at 1 under.
Seven teams share 20th place at even par including the pairing of New South Welshwoman Sarah Kemp and China's Xiyu Lin and the team of Karrie Webb and Colombian Mariajo Uribe.
This week also presents a great opportunity for Kemp who, at 64th on the standings, can move back inside the all-important top 60 which will eventually qualify for the 4-week Asian swing leading into November's season-ending Tour Championship.
The Dow Great Lakes Bay Invitational - the first official two-person teams event in LPGA history - alternates between foursomes for rounds one and three and four-ball for the second and final rounds.
The field of 70 teams will be cut in half after 36 holes.
