It appears that 91.50 is the correct amount for a $4 toll that went unpaid for more than 42 days. EZ Pass violation notices can be appealed.
Your communication is apparently from a debt collector. You may demand evidence that the debt is valid before deciding whether to pay or contest the alleged debt. Or you can go straight to the Delaware EZ Pass authorities.
According to this official EZ Pass FAQ:
Q: What do I do if I receive a Violation Notice?
A: A Toll Violation Notice is issued for every violation (see example). In addition to the toll, a Violation Notice has a $25 Administrative Fee, $10 Ambulance Company Fund Fee, and a $15 fee to Combat Violent Crimes.
A Toll Violation Final Notice (see example) is issued if the Violation Notice has not been paid within 30 days. The Toll Violation Final Notice adds a Civil Penalty of $25 and a Civil Penalty Surcharge of $12.50 to the fees listed on the first Notice of Toll Violation. If the Toll Violation Final Notice is not paid, it will be subject to registration hold, collection activities or legal action.
Those fees would add up to $91.50 on a $4 toll if a violation went unpaid for 30 days or more. Note that the "violent crimes part" is to fund the "Combat Violent Crimes" program, not because a toll violation is itself violent.
The FAQ goes on to state:

The "amnesty" program is describe on the page "Motorists who violated Delaware tolls to get 3 months to settle up with severely reduced penalties ", which states:
Anyone in arrears who committed a violation between January 1, 2014, and April 30, 2020, will receive a notification of the program to settle the debt owed plus an additional amnesty fee.
The bill details that a person who fails to pay a $1 toll typically incurs the following penalties:
- an administrative fee of $25;
- a civil penalty of $25;
- for violations that occurred after January 31, 2017, a $10 fee for the Volunteer Ambulance Company Fund
- for violations that occurred after January 31, 2017, a $15 fee for the Fund to Combat Violent Crimes.
- In addition, a civil penalty surcharge of $12.50 is added for each toll violation that remains unpaid after 42 days
Ultimately, a $1 debt can increase to $51 initially, and then $88.50 after 42 days. Under the new bill, the amnesty fee is applied on a sliding scale, with penalties further reduced based on the increasing number of violations one may have incurred.
The resolution creating the amnesty program reads, in pertinent part:
BE IT FURTHER RESOLVED that the Amnesty Program will be designed as follows:
(1) Include toll violations that occurred on I-95 or SR 1 between January 1, 2014 through April 30, 2020 but does not apply retroactively.
(2) Include toll violations by residential and commercial vehicles registered in any state.
(3) Satisfies toll debt if all of the following is paid:
a. The full amount of the unpaid tolls.
b. In lieu of the outstanding administrative fees and civil penalties, an amnesty fee as follows:
- For up to 10 toll violations, $60.00.
- For 11 through 50 toll violations, $135.00.
