Lasitskene wants the IOC president to end sanctions against Russian athletes.
Russian and Belarusian athletes were recommended to be banned from competing by the IOC.
"Your decision did not stop the war but gave birth to a new one," Lasitskene wrote in an open letter.
It's not true that you said you made the decision for our safety.
Lasitskene, who won gold at Tokyo 2020, has been banned from international competition since World Athletics excluded "all athletes, support personnel and officials from Russia and Belarus" from World Athletics Series events, following the IOC's recommendation.
The three-time world champion missed out on the Olympics when Russia was punished for DOPING.
She competed as a neutral athlete in the Tokyo Olympics and won two world titles.
Lasitskene didn't have the chance to compete in international competition for about four years.
My Russian passport is used as a trump card by World athletics. You didn't see any problems with this. They are doing this again at your direction.
The 29-year-old accused the IOC of preferring to know nothing of the opinions of Russian athletes and how they live.
The girls I work with in the high jump sector are Ukrainian. She didn't know what to say to them or how to look at them.
They and their friends and relatives are experiencing something no one else should.
Russian athletes, officials and teams have been banned from international events by many sport federations.
According to Lasitskene, the IOC chose the "easiest solution" in banning athletes because of their citizenship.
She thinks that you won't have the courage to end the sanctions against Russian athletes.
