Hi JFK, welcome aboard.
What I would probably do is find cuisines that do not use tomatoes and see if I like them.
Tomatoes come from the New World, the Americas. Most Asian cooking does not incorporate them (although there was a lot of, for example, French influence in Asian cuisine and they do incorporate tomatoes at times.)
Good grief, Indian cuisine is fantastic. Nary a tomato there. Ok rarely.
Traditional German, Hungarian, Eastern European cuisine is not laden with tomatoes.
Many Mexican and Central and South American dishes are devoid of the love apple.
Were I scratched with an allergy to a product would probably search for dishes that dis not incorporate it.
There are so many dishes that do not incorporate tomatoes.
Don't let a little allergy stop you from cooking.
Good luck.
