Yes, a trustee can be sued for breaching their duties — especially if their actions resulted in financial harm to the trust or its assets.

Legal action against a trustee may seek to suspend, remove or surcharge them. If their misconduct caused significant losses, you might also be able to recover damages and impose a surcharge to hold them financially liable.
