Not at all. Most RPGs are based around levels, but in a well designed one you never have to linger in an area to grind. If you run from fights all the time you're in trouble. If you fight what's presented to you you'll have acceptable damage numbers by the end of the game, with an experience curve that allows you to catch up quickly in later areas.
After that in some RPGs, for bonus dungeons designed around mechanics abuse they hand you tools or have existing systems that change up the gameplay focus, and the idea behind it is you have to find a way to get to max level and set up to abuse the game to it's fullest.
For example in Star Ocean 3, you're presented with enemies in the Sphere tower dungeon that can one-shot you easily, so you have to take full advantage of equipment customization to skyrocket your stats, you can either grind or set up your equipment so it gives you max stats, which is easy since all that entails is making 3 sets of expensive boots, upgrading them so their effects are boosted, then copy-pasting their +30% stat boosts over an over 9 times on a generic weapon, like on a Laser Sword that can be equipped to anyone and is easily available.
The effect boosts your stats to max when you compound it with stat-boosting gear or +2000 Attack boost effects and so on.
On top of that, if you do well in combat in a certain way, like killing enemies with a special attack, you can grossly enhance your EXP gain up to about 300%-500%.
This combined with a status infliction weapon, like a Laser Sword or Gun with a Freeze chance on hit, compounded with multi-hit effects and a Light Ball homing missle-on-attack effect that's normally a gimmick that does little damage but has a different element, you can make a 1-Hit KO weapon that compounds when you use multi hit attacks, which one of your ranged party members, Maria, has plenty of, and her Ultimate skill is practically made for this since it uses her Fury points as ammo.
So, with your stat-maxing gear and 1-hit KO gun alongside your 500% exp battle bonus, you can go fight certain enemies, specifically Fish enemies on the first floor of that dungeon since they have the least resistance, you can take a character from Level 1 or otherwise to Level 200 in three battles due to how EXP is ridiculous in the dungeon since all enemies are max level.
On top of that there's gear that boosts EXP gain but increases damage you take by x3, so you could do it in one.
And THAT is how well designed RPGs handle grinding. When you get down to it, RPGs are about figuring out a system and abusing it like a massive puzzle with variable solutions. Loads of games don't do that anymore because the AAA industry only grasped that "RPGs = numbers or some shit"
