I'm trying to debug why my cron job is not working

Here's what I have so far:

* * * * * /bin/echo "cron works" >> /tmp/test_cron_hello <-- WORKS
* * * * * cd ~/bot-v2 & date >> /tmp/test_cron_hello <-- WORKS
* * * * * cd ~/bot-v2 & date >> logs/cron.txt <-- DOES NOT WORK

I know that ~/bot-v2/logs/cron.txt is a valid file and folder and I am running crontab -e as root.

You need && instead of &.

Explanation:

If a command is terminated by the control operator &, the shell executes the command in the background in a subshell. (man bash)

& will send the command (cd ~/bot-v2) to background and it will run in a subshell, so for the next command date >> relative/path/to/file you are not changing directories at all.

Try cd ~/bot-v2 & in terminal and you will see that your current shell won't change directories.
