If a participant has terminated employment with a small vested benefit/account balance, the law gives the plan administrator (consistent with applicable plan provisions) the authority to force them out. Best is for the participant to say how they want it distributed. Failing that, the plan administrator, having made a suitable effort to find and/or communicate with the participant, has the right to cash the small amount out. Unless the plan administrator fails to exercise due prudence in the selection of the default IRA provider (which might not even be subject to the same degree of scrutiny as other fiduciary acts), the expenses charged by the default IRA provider are of no consequence to the plan administrator. Remember, if the amount payable is over $200, there would have been an opportunity provided for the participant to choose between a lump sum or a direct rollover, and only if there is no timely response can the money be sent on the IRA provider, so the participant, by failing to keep in touch with the sponsor and/or to respond to the election that was offered, is at least partially at fault. The plan will not afford veto power over the distribution to the participant - these are involuntary by nature.
