Yes if a friendly match can end up in a tie, why does it states on the market and also on my bet that it includes overtime? are you trying to confusing the players even if you are not responsible for the information on the market?
"it includes overtime" reads more like should there be one, the game that you bet on did not have one, period.
The three most popular markets in basketball: moneyline, spread, and total by default include overtime. Some bookmakers have it written like Sb in brackets some don't, but it does almost always include overtime (should there be one played).
1. I can find more examples from the friendly matchesi with overtime. Even if it is true that a friendly match can be a draw, then why can't you write about it? Or is it a random situation and players need to guess whether they will play overtime or not, is that really fair in your opinion?
I'd be surprised if there is a single bookmaker in the world where in their rules/terms and conditions is mentioned that a friendly basketball match can end in a tie. It is the responsibility of the bettors to know that even if it is an uncommon occurrence, it can happen.

In the event that a match does not finish in a tie, but overtime is played for qualification purposes, the markets will be settled according to the result at the end of regular time. You even considered the situation where there is no draw but overtime is played, but not where they played a draw game and overtime is not played. It is just your fault not to descripe that situation in the rules.
"but overtime is played for qualification purposes"
I'm pretty positive it refers to two-legged ties based on aggregate score. For example, team A wins game1 90-75 but loses game2 80-65, then overtime is played to determine which team should advance to the next round.
3. Support said in the conversation that a nba summer league game could ended with a tie, please give me a example about that. Or is the support using this reason to dismiss me?
If the support refers to the main Las Vegas summer league, then the information is incorrect. There is overtime played.
