It's complicated. GameFreak and the series in general has tried to distance themselves from that accusation, it's a real lore thing that Pokmon want to fight you because they're jealous of domesticated Pokmon and Pokmon like fighting in general, they don't actually get hurt during battles and they just get exhausted.
On the other hand even people who worked on the series have accused Pokmon of that. The late Takeshi Shudo, the headwriter of the original anime, said on his blog that Pokmon is a series about enslaving animals. At one point he calls Ash a hypocrite for saying he loves his Pokmon yet he has them fighting for his entertainment.
It gets even more complicated because Satoshi Tajiri, the man who created Pokmon, admits in his biography that the angles Pokmon fights are drawn in come from him imagining Pokemon fights as two dog owners allowing their dogs to fight. https://gamefaqs.gamespot.com/a/user_image/9/6/4/AARO5TAAEJIM.jpg This two panels come from right after Tajiri tells Ken Sugimori that Pokemon are creatures like cats and dogs. Tajiri clearly views Pokemon as creatures that are like cats and dogs in the real world, not only does he reinforce this view in his biography but he was also saying that even back in 1995. Books released by GameFreak during that era describe Pokemon as creatures that are friends to humans like cats and dogs and Tajiri personally wrote that Pokemon are Kaiju-like pets in a book on game design he wrote in 1995.
On top of that the series makes a very concentrated effort to build Pokemon to be like cats and dogs. Many interactions with the player mirror that of real interactions people have with their pets like playing fetch, petting them, washing them and Pokemon toys even resemble real world pet toys. Even the Pokemon behave like pets. HGSS had all Pokemon barking, nibbling on grass and even chewing on their trainer's shoes. https://www.pokecommunity.com/showthread.php?t=210589 Scarlet and Violet have pokemon running in circles around the player while being happy which is something real life cats and dogs do, and Pokemon randomly fall asleep on the floor when let out of their pokeball, they essentially act like dogs.
So it's not very cut and dry. While GameFreak has tried to not portray it that way it's also hard not to see it that way especially with the way they portray pokemon. I don't think it promotes it, kids aren't going to make their pet dogs fight me thinks, but it's difficult not to think of it that way.
This is the problem with someone unfamiliar with cultural aspects in Japan -- It's based on insect collecting, and one of the things they do when they collect insects (No, this isn't like butterfly collecting where they kill them), they keep them alive and well fed -- they even have cages specifically designed for this (Mushi Kago):
They also collect Horn Beetles, and they are popular for fights (and unlike Cock-fighting, etc...) Horn beetles just push each other off a log, and there's a minuscule chance of injury for the Horn Beetles during this, literally none they just fall off uninjured, basically, but it is an exciting battle to watch and often there is gambling done on it.
