The site receives 2k users per day with approximately the following user agents:

I think these versions of Chrome it doesn’t happen and the version is somehow generated, because on good traffic in 90% of cases the browser version:
Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.77 Safari/537.36
Is it possible to understand only by the version that the user is a Bot?
And where can I find a list of all versions of Chrome that might be?

well, you can - chrome is updated automatically and the versions of the bots will stand out from the statistical series. But this is exactly until you start blocking bots by version, it is not difficult to automatically update the UserAgent string.

Try to filter good traffic in Google Analytics and see what the graph of the remaining traffic looks like, maybe the bots will not change depending on holidays, weekends or time of day, maybe some traffic suddenly appeared on the site, or the behavior pattern of the bots is always the same (zero view time, view the same page with the same time) This is a good chance to pump analytical skills.
I had a similar story, when the client was sure that 25 percent of the traffic was IE11, it turned out that all traffic from IE11 after they hired SEO got bounced (zero or near zero watch time), and the graph for this traffic was even a strip just about from the beginning of SEO work (apparently the SEO specialist turned out to be quite stupid).
