They don't have to play all seven innings, provided they have played a requisite number of innings (not sure what the threshold is in softball). But Stanford really needs to win Game #2, because if the series is tied, or I think even if the series were to hypothetically end 1-0 in terms of games, Duke would advance on account of higher seed!

If super-regional cannot be completed, the rule of which team moves on is:
0 games played Highest seed 
1 game played Winner of Game 1 
2 games played If each team has a loss, the highest seed

The rules appear to say one cannot play two games on day one, though the overall wording is ambiguous and there is a typo. 
"Super Regional Format. In all two-team super regional tournaments, Game 1 will be played on the first day; Game 2 on the second; and Game 3 (if necessary) on the third day. If there is a weather delay during super regional competition, teams will have three days to complete the super regional competition before the inclement weather policy will be applied." 
I think it is actually that teams will have FOUR days to complete the super regional competition. If not, then they cannot play a game on Monday, which would be the fourth day. 
The three days thing is actually written down in two different places. 


The 2021 rules state (more or less) that seven innings need to be completed for the game to count,
"If play is stopped before a seven inning game is completed and the eight-run rule is not in effect, it will resume at the point of interruption."
The 2023 version doesn't seem to directly address the point directly and only says, 
"All games will be scheduled for seven innings. However, a five-inning, eight-run rule will be used in all rounds of the championship, including the championship best-of-three series."
