Should I contribute to a traditional IRA if my income is above limits for tax deductions?

I was looking at my ProjectionLab plan and I noticed that it wasn't contributing to my traditional IRA accounts. When I looked into it, it said that it won't contribute to an IRA if your income is above the max for tax deductions. I had IRAs so engrained in my thinking, that this was the first time I had even thought about whether a traditional IRA was even getting me anything since my income is too high to take the deduction. I'll obviously continue contributions to my 401K, but should I switch to making contributions to a taxable brokerage account instead of our traditional IRAs?
