Should I play computer to avoid cheater in longer time controls?

You play against cheater (chess engine) lol

No, just check the computer analysis after the game to take stock of all the mistakes and blunders your opponent made and how you took advantage or not. I think the big money over the board tournaments are toast due to the seemingly widespread prevalence of the hidden stockfish trick.

Yeah.

So basically, I'm trying to play in a very long time control but I don't wanna meet a cheater. I mean, that feeling sucks and I don't want to feel that again. Does playing against a computer (say level 6 or 7) good instead than a human that can cheat?
If you are playing chess only to get Lichess rating points, then perhaps you need to reconsider the reason you are playing. You are definitely good enough to get a game over the board, meeting players and having fun with them is a very large part of chess. If you use Lichess for that end, then you can improve your game on here however you like, but playing against humans is better for finding typical human weaknesses which you might expect to see over the board.

There are very few cheaters on Lichess. You may play against a cheater, but there is no reason to get despondent about it, they are not prevalent and they don't get anything for their troubles. They win fake Elo, it is in fact only to find more suitable opponents on this site. That's why cheating on Lichess is pointless, they are cheating themselves into playing against people they have even less chance of having a decent game against!

Cheaters are definitely not good for the game. Only that it is definitely not benefitting them, it is only helping their ego temporarily deal with losing to better chess players. When they play their own moves, they have to realise how much ahead of them everyone else is.

You however, get to play against someone who makes no mistakes, which helps you to get a better insight into your genuine weak points without having the expectancy of losing to a computer, and get better balance by being able to fix them after. Just save your despondence for another time, accept the rewards now, and you may find that you get your "points" back any way!

I was going to say, whether you get matched up with a cheater (which does seem to be pretty rare) or choose to play against one of the engines, you're playing a computer either way. At least if you opt to play other lichess members, most of the time you really will be playing a person.
