First, figure out which one is the bot on the scoreboard based on score. Hold TAB to check.
In this example, the real TMF has 6 points while the fake TMF has 1 point.

Second, open up the report menu (or mute menu) to look at the playerlist. Press ESC to open up the main menu. Then click the triangular ! or the ear icon at the bottom middle of your screen.

Now, remember the player order for your teammates. The order (ignoring the enemy team) will look the same in the votekick menu. The fake TMF with 1 point is at the very top of this list. The real TMF with 6 points is right below "That Meme Patriot."

If their score is the same, you can differentiate based on the medal next to their name as it shows up in the report menu too.

Third, open up the votekick menu. Click the checkmark icon at the bottom middle of your screen.

Again, notice how the player order is the same as the report menu you just saw. The fake TMF is at the top while the real TMF is below "That Meme Patriot."

Like that, you have all the information you need to call the votekick. To repeat;
1. Compare the real player & the bots score or badge in the report menu

2. While still in this menu, check the player order (for your teammates) & locate where the real player is in comparison to the bot

3. The votekick menu will have the same player order you've just seen. Use that to kick the corresponding bot

Thanks for your time.
