LTspice time step too small error

Welcome to AAC!
The supply to your opamp is only 2.8V, single-polarity, whereas the OPA134 datasheet specifies a minimum ±2.5V dual-polarity supply.
If the opamp model isn't working properly, try using a different model, e.g. one of the standard LTS/AD models for an opamp with a similar spec.
