The concept of italic correction does not exist in OpenType fonts (it is
a character propriety in TFM files, with no correspondence in OpenType),
so it will only work with TFM fonts.

"luaotfload" has an `itlc` option that would try to guess an italic
correction for glyphs when loading the fonts. I've no idea how reliable
is it.

Try \setmainfont[RawFeature={+itlc}]{Latin Modern Roman}, it seems to
make a noticeable improvement.

If you are using ConTeXt, Hans has some experimental features for
automatic italic correction, see
