I placed down repeating command block with command "random roll 0..71 minecraft:cmd". It sends many text to my chat. I wrote "/gamerule commandBlockOutput false", but messages still appears. I also tried sendCommandFeedback and logAdminCommands.

That's what the "roll" option is used for, announcing the results. This is comparable to saying "/say result isn't hidden by the game rules". To not announce to chat, you use "value", not "roll".
If you actually turn the command block output game rule on, and run the command block, you'll see 2 separate messages, rather than 1, per time it runs; THAT is the command block output.
