If you asked this question by yourself, here are some suggestions for you.

Keep in mind that you should get PS Plus Extra to save costs and maybe you already claim every PS Plus Essentials game even if you don't play it.

Tekken 7

Do I need to win matches online?

Yes, only one match in ranked, unranked and tournament. Very easy actually, especially since unranked and tournament can be boosted but you can win this even without boosting.

Are the trophies hard at all?

I only had bigger problems with the last fight in the story mode and maybe some fights at the end in Treasure Fight but spamming moves are possible.

Are the trophies grindy?

Only the rank trophies are grindy. Stick to your favorite spam machine and spam your way to the Warrior rank.

Are there DLC trophies?

Nope.

Mortal Kombat 11

Do I need to win matches online?

Not at all.

Are the trophies hard at all?

Only the tutorial trophies... xD You need to do some combos and that will require some tries. Nothing impossible but you will need some time to do that.

Are the trophies grindy?

Definitely but you can cheese it sometimes. 50 matches online - find someone to boost or just let the opponent win. Sometimes you find another one who wants this trophy, so just press down + triangle to do it fast.

Another grindy set of trophies are the Krypt trophies. Open 200 chests requires many coins but you should get it easily if you do every other trophy.

2 Fatalities with every character is actually easy because you can let the CPU fight for you and he will win every time.

100 Brutalities require you as the player so you can do it everytime. Just press down + triangle the whole time on difficulty Super Easy.

25 Fatalities to 5 specific characters are also grindy but also easy.

250 completed towers are actually quick because you don't need to play a full tower. Just quit out in the match of an Endless Tower and that's it. Do it after you get all the other trophies done.

Are there DLC trophies?

Not yet. Probably never. I'm not sure, MKX had a few after it was MKXL but it's already MK11 Ultimate and no trophies were added yet.

I didn't play the following two games yet but I know what to expect when I look at the trophy guide.

Guilty Gear: Strive

Do I need to win matches online?

Not at all.

Are the trophies hard at all?

Probably not, just finish story, play some online matches, do everything else in versus or with a second controller. The hardest trophy is probably the golden one because you can't lose even one round to reach the requirement. There are cheesy methods out there, I'll edit this one when I play it.

Are the trophies grindy?

As far as I can see: Not that much since you can do everything with a second controller.

Are there DLC trophies?

Nope.

Granblue Fantasy: Versus

According to the guide on PSNProfiles you need the DLC. This info is old, they fixed it, you don't need the DLC anymore.

Do I need to win matches online?

Only one match. You can boost that in a private room.

Are the trophies hard at all?

Probably the combo trophy. We all know how much combos suck with so many different button inputs. I can't say much because I still need to play it.

Are the trophies grindy?

Several trophies where you need to do something 50 or 100 times. At the end just some are left but it's still grindy.

Are there DLC trophies?

Nope, not at all and again, you don't need the DLC. I will play this game and try to confirm it again but the PSNProfiles guide is dated.
