Neeko has a around 49.81 winrate in low elos but around 50 to 51 percent winrate in higher elo

She's basically 50% is what you're saying

So no, he doesn't need a buff at all

Shes at 50% winrate and you are asking for buffs

There are champs who are struggling to get anywhere near a 50% winrate at all and you want this champ to be buffed?

Neeko's kit is so disgustingly safe, what reason could she need a buff? Both her Q and E ignore the minion wave (Her E being empowered by it)
