Questions & Answers about kare wa watashi o mondai ni makikonda.
は marks 彼 as the topic of the sentence: as for him, he got me involved in a problem.
If you used が instead, the sentence would sound more like you are specifically identifying him as the person who did it:
- 彼は私を問題に巻き込んだ。 = He got me involved in a problem. / As for him, he got me involved...
- 彼が私を問題に巻き込んだ。 = He’s the one who got me involved in a problem.
So は is the more neutral topic-marking choice here.
Because 私 is the direct object of the verb 巻き込む.
The verb 巻き込む means to involve someone in something. In Japanese, the person being pulled in is marked with を:
- 私を = me
- 問題に = into a problem / in a problem
- 巻き込んだ = got involved / dragged in
So the structure is basically:
[person] を [situation] に 巻き込む
= to involve [person] in [situation]
