Unlikely, since helicopters are pretty dangerous (especially cold war era ones), have a single point of failure, and the accident apparently happened in bad conditions and in a mountainous region.
Also the Iranian president is more of a state figurehead than an actual ruler with the power to change the country. The Ayatollah is the one pulling the strings.
Don’t even think Iran are going to blame this on Israel, as they would get clapped in a direct confrontation with the IDF, and they know it.
