Чтобы с

tickets = {
    1: ['API_45', 'API_76', 'E2E_4'],
    2: ['UI_19', 'API_65', 'API_76', 'E2E_45'],
    3: ['E2E_45', 'API_45', 'E2E_2'],
    4: ['E2E_9', 'API_76'],
    5: ['E2E_2', 'API_61']
}

Стало:

tickets = {
    1: ['API_45', 'API_76', 'E2E_4'],
    2: ['UI_19', 'API_65', 'E2E_45'],
    3: ['E2E_2'],
    4: ['E2E_9'],
    5: ['API_61']
}

uniqueTickets = set(sum(tickets.values(), []))

for k in tickets:
  t = uniqueTickets.intersection(set(tickets[k]))
  uniqueTickets.difference_update(t)
  tickets[k] = list(t)
