You believe that every single individual Jew was cut off?! It's a stretch to interpret Romans 11 that way, and it's clearly at odds with a lot of other scripture.
Absolutely. God cut-off the entire nation of Jews, every single, individual one.
Paul earlier explained who the true Jew is now Rom 2:28,29
Now under Christ's NT, the true Jew is
NOT one outwardly, circumcised of the flesh but the true Jew is one inwardly, circumcision of the heart, see Col 2:11 Rom 9:8 "
That is, They which are the children of the flesh, these are not the children of God: but the children of the promise are counted for the seed." Fleshly Israel is
NOT the children of God,
NOT the seed of promise now, but spiritual Jews (Christians) are the childen of God, are counted for the seed. Just fleshly descent from Abraham does not make one a child of God. Gal 3:26-28 shows how one becomes a child of God. So in Rom 9 Paul refutes the Jews argument they must be of God since they were fleshly descendants of Abraham as Paul points out God does not have to base His choices on fleshly descent. God can choose whom He decides to, He can even choose those once non-elect Gentiles if He wants to, as Paul alludes to in Rom 9:15.
Since all Israel was cut off then for a Jew to be saved he must be saved through Christ and become a true Jew, that is, obey the gospel of Christ by being water baptized, receive the "circumcision made without hands"
So under the OT all Jews, all of Israel was God's chosen and they were all cut-off and only those Jews that obeyed the gospel in Acts 2 by obeying Peter's words Acts 2:38 became a true Jew, part of God's elect. Those Jews (the majority) refused to obey and it is these Jews Paul laments over in Rom 9:3 but says these lost Jews could still be saved if they would submit/obey God's righteousness/commandments, 'but they have not all obeyed the gospel; Rom 10:16.
So those Jews/Pharisees you read about in the NT that were lost, they were lost NOT because of some capricious choice God made about certain individuals before the world began, they were lost due to their own free will in rejecting Christ and His gospel, 1 Thess 2:14-16
