I just remembered that a teenage me, probably close to 10 years ago, once made a thread on here about how to change up Pokemon, and as an EXAMPLE, I said what if they made Pokémon a third person shooter. And y'all ripped me apart for it, WHO'S LAUGHING NOW?!?
But seriously,
My guess is took the basic descriptions of Pokemon, and fed these to an AI, telling to make an anime style cartoon creature matching that description (or maybe just telling it to make a Pokemon). And since AI can only work with what already exists, they ended up with remixed versions of Pokemon. For example
"a anime-style cartoon creature that is a yellow and red rodent with a tail in the shape of a lightning bolt"

I kinda messed up on the third one because it should've been teal and not green, but let's be honest here, they still all ended up obvious expies of Pokemon i.e. Pikachu, Charizard, Venusaur and Squirtle. It even added details I didn't specify because the Pokemon has them like the red cheeks on Not-Pikachu, the wings on Not-Charizard, the pink flower on Not-Venusaur, and the brown shell on Not-Squirtle.
I think the AI conversation is a little overblown at this point. The game was revealed well before AI image generators were good enough to make more than just shitty Minions memes.
One of the most blatant ripoffs in the game is the dollar store Lucario. And it was present in their trailers as early as 2022. That doesn't mean that no designs were created with AI, but the timing means that majority of pals were likely created with minimal to no AI involvement. Unless the majority of all character design, game design, modelling, animation, and sound effects were all crammed into the last year of this game's development.
But let's say AI tech came out, the devs leaped for joy, and immediately started using it for this game to pump up the number of pals they already had. I still don't think it would have been that useful for them, even assuming the tech back then was as good as it is now.
For one, these are 2D images. The examples you attached would not at all stand up to being made 3D as is without someone making adjustments. Maybe you could prompt the generator to give you a full isometric view to mitigate this, but I don't know how well that would go. The adjustments could be as minor as removing the extra toe on your Squirtle and as major as completely rethinking the design because the proportions don't make any sense in 3D.
There's the issue of art style as well. I wouldn't say the Pals look particularly amazing, but they at least look consistent. With AI, I don't think you can guarantee that consistency. Your Pikachu is way too different from the other three, and even then the three look like they could come from different franchises.
But I think more importantly, and very well exemplified by what you generated, this AI stuff is way too close to Pokémon. The devs clearly had no qualms with copying homework, but I'm sure they did their very best to ensure that they never crossed the line. 3 years and thousands of dollars were at stake after all. And even if they did take these lawsuit-risking designs and reworked them enough to be legally distinct, then well... It's not really AI generated anymore is it?
In summary, I think using AI generated Fakemon is more of a hassle than just manually ripping off Pokemon yourself.
Yeah there's clearly a lot be discussed for this topic. I don't at all doubt that in some way, AI was used in the creation of this game. However I dispute just how much people seem to think it was involved. But how much is too much? Should game dev be completely devoid of AI? What level of usage of AI is acceptable? Once people get over their irrational love/hate of Pokemon in relation to this game, I think there will be some real discourse happening.
