Alright let's get autistic about this and used some half assed logic to prove this.
Being an idol she'd dance, sing and do events live a lot and she wears a lot of outfits that exposes her armpits, belly, legs and feet so she'd use products to make them look soft and smooth and as she wears outfits that show off her feet and she always has fresh blue nail polish she'd get pedicures a lot making her skin soft and ticklish. However, she also has outfits where Miku is completely barefoot and dancing barefoot would toughen them up a bit which makes the parts of feet that withstand the pressure less sensitive her heels, the balls of her feet and her toes but the parts that don't touch the ground would still be really ticklish like her arches and maybe between her toes.
In conclusion yeah Miku would be really ticklish.
And she'd like being tickled because involuntary laugher trains her vocal cords and stamina or some shit.
