Attorney Tony Buzbee, who is repping the family of Axel Acosta, tells TMZ ... all signs are pointing to Travis and the rest of the festival lineup going to great lengths to protect themselves from the crowd, and not putting nearly enough resources into crowd safety.

Buzbee says Axel traveled all the way from Washington to see the Houston festival and loved Travis, but the feelings were clearly not mutual, because the 21-year-old is one of 9 who perished from injuries suffered at the concert.

The way Tony sees it ... Travis and other artists are full of it when they say they love their fans, because if they really did, they would implement better safety measures at shows. Especially when they're massive 50,000-fan events like Astroworld was.

While Buzbee says he's not singling out Travis from the festival lineup, which also included Drake, watch the clip ... he clearly seems to be laying blame at the feet of the headliner.

TMZ broke the story ... Travis vowed to cover funeral costs for families of the people who died at the show, and provide mental health services to anyone impacted by the events.

Buzbee thinks that's a hollow offer -- he says the Acosta family has not heard a peep from Travis' camp and isn't expecting to get any money for Axel's upcoming funeral.

Travis' camp tells us they have been "actively exploring routes of connection with each and every family affected by the tragedy through the appropriate liaisons" ... adding families of the victims can reach out to them directly too.

Meanwhile, Buzbee is conducting his own investigation, and claims police requested full riot equipment before Astroworld's gates even opened Friday morning -- and by 10 AM cops admitted they had no control ... even with an extra 300 officers coming in to boost the overall number to 500.
