It's far easier to add than subtract, though. There are feats and races that have spells, or you could get DM permission to bring some of the magic down to 1st level. If you build in the magic from 1st, though, you take away peoples ability to grow into a concept.Yes. You cannot 'be a skilled warrior that blends bladecraft with spellcraft with absolutely no spells.
I can't get spells by just pretending to have them.
If I were to play an eldritch knight and wanted to have fighting and magic from 1st level, I'd pick ardling, Elf, gnome or tiefling, since those races have built in magic. Then I'd pick Cultist, Sage, or make up a background that has Magic Initiate(Arcane) so I can grab some battle cantrips. Poof! A skilled warrior that blends bladecraft and spellcraft, and who will get better at it at 3rd level.
